-# Trackeep Deployment Guide
-
-## Flexible Deployment Options
-
-Trackeep is designed to work in various deployment scenarios:
-
-### 1. Local Development (localhost)
-```bash
-# Start with default settings
-docker compose up -d
-
-# Frontend will be available via nginx on port 80
-# Backend API on port 8080
-# Frontend automatically detects API URL: http://localhost:8080/api/v1
-```
-
-### 2. Home Network Deployment
-```bash
-# Set your HOST environment variable
-export HOST=192.168.1.100:8080
-
-# Or modify .env
-echo "HOST=192.168.1.100:8080" >> .env
-
-docker compose up -d
-
-# Access from any device on your network
-# Frontend: http://192.168.1.100
-# API: http://192.168.1.100:8080/api/v1
-```
-
-### 3. Domain with Cloudflare/Reverse Proxy
-```bash
-# Set HOST to your domain
-export HOST=yourdomain.com
-
-# Configure CORS for your domain
-export CORS_ALLOWED_ORIGINS=https://yourdomain.com
-
-docker compose up -d
-
-# Configure Cloudflare to proxy:
-# - yourdomain.com → backend:8080
-# - app.yourdomain.com → frontend:80
-```
-
-### 4. Production HTTPS
-```bash
-# Set production mode
-export GIN_MODE=release
-export HOST=yourdomain.com
-export CORS_ALLOWED_ORIGINS=https://yourdomain.com
-
-# Use SSL certificates (via Traefik, Nginx, etc.)
-docker compose up -d
-```
-
-## Environment Variables
-
-### Core Configuration
-- `PORT=8080` - Backend port only
-- `GIN_MODE=debug|release` - Application mode
-- `HOST=` - Auto-detection fallback (optional)
-- `CORS_ALLOWED_ORIGINS=*` - Flexible CORS (restrict in production)
-
-### Removed Variables
-- ❌ `FRONTEND_PORT` - No longer needed
-- ❌ `OAUTH_PORT` - Moved to oauth-service/.env
-- ❌ `VITE_API_URL` - Auto-detected via /api/v1/config
-
-### OAuth Service (Separate)
-See `oauth-service/.env.example` for OAuth-specific configuration.
-
-## API Detection
-
-The frontend automatically detects the API URL by:
-1. Calling `/api/v1/config` endpoint
-2. Using the current request's scheme and host
-3. Falling back to `HOST` environment variable
-4. Final fallback to `localhost:8080`
-
-## Port Management
-
-- **Backend**: Fixed port 8080 (required for API)
-- **Frontend**: No port mapping (uses nginx:80 internally)
-- **OAuth**: Separate service on port 9090
-- **Database**: Port 5432 (internal to Docker network)
-
-This flexibility allows Trackeep to adapt to any deployment scenario while maintaining a consistent configuration approach.

+
+### Service Architecture
+
+Trackeep production deployment consists of **3 essential services**:
+
+#### **🎯 Frontend Service**
+- **Image**: `ghcr.io/dvorinka/trackeep/frontend:latest`
+- **Ports**: `80:80`, `443:443`
+- **Purpose**: Web interface and user experience
+- **Health**: Depends on backend service
+
+#### **🔧 Backend Service**
+- **Image**: `ghcr.io/dvorinka/trackeep/backend:latest`
+- **Ports**: `8080:8080`
+- **Purpose**: API server and business logic
+- **Health**: Built-in health check endpoint
+
+#### **🗄️ Database Service**
+- **Image**: `postgres:15-alpine`
+- **Purpose**: Data persistence and storage
+- **Health**: PostgreSQL readiness check
+- **Storage**: Persistent volume for data
+
+### Required Environment Variables
+
+Create a `.env` file from the provided `.env.example` and configure these required variables:
+
+```env
+# Database Configuration
+DB_PASSWORD=your_secure_password
+POSTGRES_PASSWORD=your_secure_password
+
+# Security Configuration
+JWT_SECRET=your_jwt_secret_key
+ENCRYPTION_KEY=your_32_character_encryption_key
+```
+
+### AI Services Configuration
+
+AI services are now configured **only within the Trackeep application**. No environment variables are needed for AI configuration. Simply:
+
+1. Start Trackeep with the basic configuration above
+2. Navigate to Settings → AI Services in the application
+3. Add your API tokens and configure AI providers in the app interface
+4. Enable/disable AI services as needed through the app settings
+
+### Version Management
+
+Trackeep uses GitHub Docker images with the `:latest` tag. The application version is automatically managed through the Docker image tags and update checking is handled through the OAuth service. No manual version configuration is needed in the environment variables.
+
+### Version Detection
+
+The system automatically detects the running version through multiple methods:
+
+- **Docker Detection**: Identifies container image tags
+- **Environment Variables**: Uses `TRACKEEP_VERSION` if set
+- **Version Files**: Reads from `/app/VERSION` or similar
+- **Git Tags**: Detects version when running from source
+
+Access version information via the API:
+```bash
+curl http://localhost:8080/api/version
+```
+
+All other variables have sensible defaults and can be configured as needed.

 ## Introduction
 
 I built Trackeep because I was tired of juggling a dozen different apps for my digital life. You know how it is – bookmarks in one place, tasks in another, random notes scattered everywhere, and that great article you meant to read somewhere in your browser history.

+# Trackeep Auto-Update System
+
+This system provides automated daily updates for Trackeep using Docker pulls from GitHub Container Registry.
+
+## Overview
+
+The auto-update system pulls specific tagged images daily:
+- `ghcr.io/dvorinka/trackeep/backend:main-aef1e39`
+- `ghcr.io/dvorinka/trackeep/frontend:main-aef1e39`
+
+## Files Created
+
+### 1. Production Docker Compose
+- **File**: `docker-compose.prod.yml`
+- **Purpose**: Uses pre-built images instead of local builds
+- **Images**: Uses the specific tagged versions you specified
+
+### 2. Auto-Update Script
+- **File**: `scripts/auto-update.sh`
+- **Purpose**: Main script that performs the update process
+- **Features**:
+  - Checks for new images
+  - Creates automatic backups
+  - Updates services safely
+  - Health checks after update
+  - Comprehensive logging
+
+### 3. Cron Setup Script
+- **File**: `scripts/setup-auto-update.sh`
+- **Purpose**: Sets up daily cron job at 2 AM
+- **Schedule**: Daily at 2:00 AM
+- **Alternative**: Can be run manually
+
+### 4. SystemD Service Setup
+- **File**: `scripts/setup-systemd-update.sh`
+- **Purpose**: Alternative to cron using systemd timers
+- **Schedule**: Daily with randomized delay (up to 1 hour)
+- **Benefits**: More reliable than cron, better logging
+
+## Quick Start
+
+### Option 1: Cron Setup (Recommended for simplicity)
+```bash
+# Setup daily auto-update at 2 AM
+sudo ./scripts/setup-auto-update.sh
+
+# Check status
+./scripts/setup-auto-update.sh status
+
+# Test manually
+./scripts/setup-auto-update.sh test
+
+# Remove later if needed
+sudo ./scripts/setup-auto-update.sh remove
+```
+
+### Option 2: SystemD Setup (More robust)
+```bash
+# Install systemd service
+sudo ./scripts/setup-systemd-update.sh
+
+# Check status
+./scripts/setup-systemd-update.sh status
+
+# Test manually
+sudo ./scripts/setup-systemd-update.sh test
+
+# Remove later if needed
+sudo ./scripts/setup-systemd-update.sh remove
+```
+
+### Option 3: Manual Execution
+```bash
+# Run auto-update manually
+./scripts/auto-update.sh
+
+# View logs
+tail -f /var/log/trackeep-auto-update.log
+```
+

+
+### Manual Recovery
+```bash
+# Check what's running
+docker compose -f docker-compose.prod.yml ps
+
+# View logs
+docker compose -f docker-compose.prod.yml logs
+
+# Manual restart
+docker compose -f docker-compose.prod.yml restart
+
+# Restore from backup
+./backups/auto-update-YYYYMMDD_HHMMSS/
+```
+
+## Customization
+
+### Change Update Frequency
+**Cron**: Edit crontab entry
+```bash
+crontab -e
+# Change "0 2 * * *" to desired schedule
+# Examples:
+# "0 */6 * * *"  - Every 6 hours
+# "0 2 * * 1"    - Weekly on Monday
+# "0 2 1 * *"    - Monthly on 1st
+```
+
+**SystemD**: Edit timer file
+```bash
+sudo systemctl edit trackeep-auto-update.timer
+# Change OnCalendar=daily to desired schedule
+```
+
+### Change Images

+3. Restart services: `docker compose -f docker-compose.prod.yml up -d`
+
+### Add Notifications
+Edit `scripts/auto-update.sh` to add email/webhook notifications in the success/failure sections.
+
+## Security Considerations
+
+- ✅ Images pulled from trusted GitHub Container Registry
+- ✅ Specific tags prevent unexpected updates
+- ✅ Backups created before changes
+- ✅ Health checks prevent broken deployments
+- ⚠️ Ensure proper file permissions on backup directory
+- ⚠️ Monitor log file size (add log rotation if needed)

+# Redis Architecture Analysis for Trackeep
+
+## Executive Summary
+
+**Trackeep** is a self-hosted productivity and knowledge management platform built with Go (Gin framework), PostgreSQL, and React. The application already includes the `go-redis/redis/v8` dependency but currently operates with in-memory fallbacks for caching, sessions, and rate limiting. This analysis evaluates Redis deployment across multiple dimensions to determine architectural alignment and implementation strategy.
+
+**Current Infrastructure:**
+- **Backend:** Go 1.24 with Gin web framework
+- **Database:** PostgreSQL 15 (primary data store)
+- **Frontend:** React + TypeScript + Vite
+- **Deployment:** Docker Compose (single-node, self-hosted)
+- **Current Caching:** In-memory maps with mutex locks
+- **Current Sessions:** In-memory map storage
+- **Current Rate Limiting:** Per-instance in-memory tracking
+
+---
+
+## 1. Use Case Analysis
+
+### 1.1 Caching Frequently Accessed Database Queries
+
+**Current State:**
+The application uses [`MemoryCache`](backend/middleware/memory_cache.go:21) with `sync.RWMutex` for thread-safe in-memory caching. Cache entries expire via a cleanup goroutine running every minute.
+
+**Redis Opportunity:**
+
+| Query Pattern | Current Implementation | Redis Benefit |
+|---------------|---------------------|---------------|
+| User profiles | Direct DB query on each request | Cache for 5-15 min, reduces user table queries |
+| Search results | Computed on every search | Cache complex searches for 5-10 min |
+| Analytics dashboards | Aggregated from multiple tables | Cache pre-computed aggregations for 1 hour |
+| Learning paths/courses | Filtered queries with joins | Cache popular paths for 30 min |
+| YouTube channel data | Database cache + in-memory fallback | Unified Redis cache with TTL |
+| Marketplace items | Sorted/filtered queries | Cache trending/top-rated items |
+
+**Specific High-Value Caches:**
+
+1. **Enhanced Search Cache** ([`search_enhanced.go`](backend/handlers/search_enhanced.go:73))
+   - Complex multi-table searches across bookmarks, tasks, notes, files
+   - Redis can cache results with content-type aggregation
+   - Suggested TTL: 5 minutes for dynamic content
+
+2. **Analytics Dashboard Cache** ([`analytics.go`](backend/handlers/analytics.go:24))
+   - Expensive aggregations across analytics, learning, GitHub, habit tables
+   - Pre-computed dashboard data can be cached for 15-30 minutes
+   - User-specific caching with tags for invalidation
+
+3. **AI Recommendations Cache** ([`ai_recommendations.go`](backend/handlers/ai_recommendations.go:49))
+   - ML-generated recommendations are expensive to compute
+   - Cache recommendation lists per user for 1 hour
+   - Cache recommendation statistics for 30 minutes
+
+**Implementation Approach:**
+```go
+// Cache key structure
+trackeep:{resource}:{user_id}:{query_hash}
+trackeep:search:{user_id}:{md5(query+filters)}
+trackeep:analytics:dashboard:{user_id}:{date_range}
+trackeep:recommendations:{user_id}:{type}
+```
+
+### 1.2 Distributed Session State Management
+
+**Current State:**
+The [`RedisSessionStore`](backend/middleware/session.go:36) struct exists but uses `map[string]*SessionData` as a fallback in-memory store. Sessions are lost on server restart and don't work across multiple backend instances.
+
+**Session Data Structure:**
+```go
+type SessionData struct {
+    UserID     uint      `json:"user_id"`
+    Email      string    `json:"email"`
+    Username   string    `json:"username"`
+    Role       string    `json:"role"`
+    SessionID  string    `json:"session_id"`
+    IPAddress  string    `json:"ip_address"`
+    UserAgent  string    `json:"user_agent"`
+    CreatedAt  time.Time `json:"created_at"`
+    LastActive time.Time `json:"last_active"`
+}
+```
+
+**Redis Implementation:**
+- Use Redis Hash or JSON data type for session storage
+- TTL: 24 hours (matching current cleanup logic)
+- Enable session persistence across deployments
+- Support horizontal scaling of backend instances
+- Session invalidation on logout/password change
+
+**Key Pattern:**
+```
+trackeep:session:{session_id} -> SessionData (JSON)
+trackeep:user:sessions:{user_id} -> Set of active session IDs
+```
+
+### 1.3 Real-Time Leaderboards and Rate Tracking
+
+**Current Opportunities:**
+
+1. **Community Challenges Leaderboard** ([`community.go`](backend/handlers/community.go:1))
+   - Track challenge participants and completion rates
+   - Real-time leaderboard updates
+   - Redis Sorted Sets (`ZADD`, `ZREVRANGE`) ideal for ranking
+
+2. **Marketplace Item Rankings** ([`marketplace.go`](backend/handlers/marketplace.go:1))
+   - Sort by downloads, rating, views
+   - Trending items calculation
+   - Redis can maintain real-time counters
+
+3. **User Analytics Streaks** ([`analytics.go`](backend/handlers/analytics.go:786))
+   - Learning streaks tracking
+   - Daily habit completion counts
+   - Redis counters with daily windows
+
+**Implementation:**
+```go
+// Challenge leaderboard
+trackeep:challenge:{id}:leaderboard -> Sorted Set (score: completion_time, member: user_id)
+
+// Marketplace trending
+trackeep:marketplace:trending -> Sorted Set (score: view_count_24h, member: item_id)
+
+// User learning streaks
+trackeep:user:{id}:learning_streak -> Hash (current_streak, last_date, max_streak)
+```
+
+### 1.4 Rate Limiting
+
+**Current State:**
+The [`RateLimiter`](backend/middleware/rate_limiter.go:13) uses in-memory `map[string]*ClientInfo` with per-IP tracking. This doesn't work across multiple instances and is vulnerable to restart clearing.
+
+**Redis-Based Rate Limiting:**
+
+| Rate Limit Type | Window | Current Limit | Redis Strategy |
+|-----------------|--------|---------------|----------------|
+| General API | 1 minute | 100 requests | Sliding window with `ZADD` |
+| Search | 1 minute | 100 requests | Fixed window with `INCR` + `EXPIRE` |
+| AI Chat | 1 minute | 20 requests | Token bucket algorithm |
+| Login attempts | 5 minutes | 5 attempts | Count with `INCR` + longer TTL |
+| File uploads | 10 minutes | 10 uploads | Sliding window per user |
+
+**Token Bucket Implementation:**
+```go
+// Redis Lua script for atomic token bucket
+local key = KEYS[1]
+local capacity = tonumber(ARGV[1])
+local refill_rate = tonumber(ARGV[2])
+local now = tonumber(ARGV[3])
+
+local bucket = redis.call('HMGET', key, 'tokens', 'last_refill')
+local tokens = tonumber(bucket[1]) or capacity
+local last_refill = tonumber(bucket[2]) or now
+
+local delta = math.min(capacity, tokens + (now - last_refill) * refill_rate)
+
+if delta >= 1 then
+    redis.call('HMSET', key, 'tokens', delta - 1, 'last_refill', now)
+    redis.call('EXPIRE', key, 3600)
+    return 1
+else
+    redis.call('HMSET', key, 'tokens', delta, 'last_refill', now)
+    redis.call('EXPIRE', key, 3600)
+    return 0
+end
+```
+
+### 1.5 Publish-Subscribe Messaging Patterns
+
+**Current State:**
+Real-time messaging uses WebSocket hub [`MessagesHub`](backend/services/messages_realtime.go:28) with in-memory `conversationClients` map. This is single-node only.
+
+**Redis Pub/Sub for Multi-Node:**
+
+1. **Cross-Instance Message Broadcasting**
+   - When horizontal scaling is needed, Redis Pub/Sub connects multiple backend instances
+   - Pattern: `trackeep:messages:{conversation_id}`
+
+2. **Notification System**
+   - Real-time notifications for new followers, messages, mentions
+   - Pattern: `trackeep:notifications:{user_id}`
+
+3. **System Events**
+   - Cache invalidation broadcasts
+   - Configuration updates
+   - Analytics aggregation triggers
+
+**Implementation:**
+```go
+// Subscribe to conversation messages
+pubsub := redisClient.Subscribe(ctx, "trackeep:messages:123")
+
+// Publish message to all nodes
+redisClient.Publish(ctx, "trackeep:messages:123", messageJSON)
+```
+
+---
+
+## 2. Data Access Patterns and Latency Requirements
+
+### 2.1 Current Database Access Patterns
+
+Based on code analysis, the application exhibits these access patterns:
+
+| Pattern | Frequency | Tables | Latency Sensitivity |
+|---------|-----------|--------|---------------------|
+| User authentication | High | users | Very High (< 100ms) |
+| Search queries | Medium-High | bookmarks, tasks, notes, files | High (< 500ms) |
+| Analytics aggregation | Medium | analytics, learning_analytics | Medium (< 2s) |
+| Message retrieval | High | messages, conversations | High (< 200ms) |
+| AI recommendations | Low-Medium | ai_recommendations | Low (< 5s acceptable) |
+| Marketplace browsing | Medium | marketplace_items | Medium (< 1s) |
+| Audit logging | High (write) | audit_logs | Low (async) |
+
+### 2.2 Latency Requirements Analysis
+
+**Critical Paths for Redis Caching:**
+
+1. **Authentication Flow** (Target: < 100ms)
+   - Current: DB query for user + session lookup
+   - With Redis: Session cache + user profile cache
+   - Expected improvement: 60-80% latency reduction
+
+2. **Dashboard Load** (Target: < 500ms)
+   - Current: Multiple aggregation queries
+   - With Redis: Pre-computed analytics cache
+   - Expected improvement: 70-90% latency reduction
+
+3. **Search Results** (Target: < 300ms)
+   - Current: Full-text search across 4+ tables
+   - With Redis: Cached results for common queries
+   - Expected improvement: 50-80% latency reduction
+
+### 2.3 Cache Invalidation Strategy
+
+**Event-Based Invalidation:**
+
+| Data Type | Cache Keys | Invalidation Trigger |
+|-----------|------------|---------------------|
+| User profile | `user:{id}:profile` | User update, password change |
+| Search results | `search:{user_id}:*` | Any content creation/update |
+| Analytics | `analytics:{user_id}:*` | Daily aggregation job |
+| Recommendations | `recommendations:{user_id}:*` | New interaction, daily refresh |
+| Marketplace | `marketplace:*` | New item, rating update |
+
+**Implementation:**
+```go
+// Invalidate user-specific cache on update
+func (h *UserHandler) UpdateUser(c *gin.Context) {
+    // ... update logic ...
+    
+    // Invalidate cache
+    redisClient.Del(ctx, fmt.Sprintf("trackeep:user:%d:profile", userID))
+    redisClient.Del(ctx, fmt.Sprintf("trackeep:analytics:dashboard:%d:*", userID))
+}
+```
+
+---
+
+## 3. Scalability Needs Assessment
+
+### 3.1 Current Architecture Constraints
+
+**Single-Node Limitations:**
+- Docker Compose deployment targets single-node self-hosting
+- In-memory caches limit horizontal scaling
+- WebSocket hub cannot distribute across nodes
+- Session storage doesn't persist restarts
+
+**Growth Projections:**
+
+| Resource | Current (Single User) | Projected (100 Users) | Projected (1000 Users) |
+|----------|----------------------|----------------------|----------------------|
+| Session storage | ~5KB | ~500KB | ~5MB |
+| Cache data | ~10MB | ~100MB | ~500MB |
+| Rate limit state | ~1KB | ~100KB | ~1MB |
+| Real-time subscribers | 1-5 | 50-200 | 200-500 |
+
+### 3.2 Redis Clustering Requirements
+
+**Phase 1: Single Redis Instance (Current Scale)**
+- Suitable for < 100 concurrent users
+- 1GB RAM allocation sufficient
+- No clustering complexity
+
+**Phase 2: Redis Sentinel (High Availability)**
+- Required for production reliability
+- 1 master + 2 replicas minimum
+- Automatic failover capability
+
+**Phase 3: Redis Cluster (Horizontal Scale)**
+- Required for > 1000 concurrent users
+- 6+ nodes (3 masters + 3 replicas)
+- Data sharding across nodes
+
+**Recommendation for Trackeep:**
+Given the self-hosted nature and typical deployment size (small teams), **Redis Sentinel** provides the best balance of high availability without excessive complexity.
+
+---
+
+## 4. Persistence and Memory Optimization
+
+### 4.1 Persistence Configuration
+
+**Redis Persistence Options:**
+
+| Option | Configuration | Use Case |
+|--------|--------------|----------|
+| RDB (Snapshot) | `save 900 1`, `save 300 10` | Point-in-time recovery, minimal overhead |
+| AOF (Append-Only) | `appendonly yes`, `appendfsync everysec` | Durability, zero data loss |
+| Hybrid | Both enabled | Maximum protection |
+
+**Recommendation for Trackeep:**
+```conf
+# redis.conf recommendations
+save 900 1
+save 300 10
+save 60 10000
+appendonly yes
+appendfsync everysec
+auto-aof-rewrite-percentage 100
+auto-aof-rewrite-min-size 64mb
+```
+
+**Rationale:**
+- Sessions should survive restarts (use AOF)
+- Cache can be rebuilt from DB (RDB sufficient)
+- `everysec` provides good balance of durability/performance
+
+### 4.2 Memory Optimization Strategies
+
+**Estimated Memory Usage:**
+
+| Data Type | Entries | Entry Size | Total |
+|-----------|---------|------------|-------|
+| Sessions | 1000 | ~500 bytes | 500 KB |
+| User caches | 1000 | ~2 KB | 2 MB |
+| Search caches | 5000 | ~10 KB | 50 MB |
+| Analytics caches | 1000 | ~5 KB | 5 MB |
+| Rate limit buckets | 10000 | ~100 bytes | 1 MB |
+| Real-time pub/sub | 500 | ~200 bytes | 100 KB |
+| **Total** | | | **~60 MB + overhead** |
+
+**Memory Optimization Techniques:**
+
+1. **Compression**
+   ```go
+   // Use MessagePack or gzip for large cached data
+   import "github.com/vmihailenco/msgpack/v5"
+   
+   func compressCache(data interface{}) ([]byte, error) {
+       return msgpack.Marshal(data)
+   }
+   ```
+
+2. **Key Naming Optimization**
+   ```
+   # Short prefixes
+   tk:u:1234:profile (instead of trackeep:user:1234:profile)
+   
+   # Hashed identifiers for long IDs
+   tk:s:8f3d2c... (MD5 hash of session data)
+   ```
+
+3. **TTL Strategy**
+   ```go
+   const (
+       SessionTTL = 24 * time.Hour
+       UserCacheTTL = 15 * time.Minute
+       SearchCacheTTL = 5 * time.Minute
+       AnalyticsCacheTTL = 1 * time.Hour
+       RateLimitTTL = 1 * time.Hour
+   )
+   ```
+
+### 4.3 Data Eviction Policies
+
+**Recommended Configuration:**
+```conf
+maxmemory 256mb
+maxmemory-policy allkeys-lru
+```
+
+**Policy Selection:**
+- `allkeys-lru`: Best for cache-heavy workloads (recommended)
+- `volatile-lru`: If some keys must persist
+- `noeviction`: Fail writes at memory limit (not recommended)
+
+**Key Expiration Strategy:**
+- Sessions: 24h TTL with refresh on activity
+- Search results: 5m TTL
+- Analytics: 1h TTL
+- Rate limits: Window-based TTL
+
+---
+
+## 5. Integration Challenges and Solutions
+
+### 5.1 Existing Technology Stack Integration
+
+**Go + Gin Integration:**
+
+```go
+// config/redis.go
+package config
+
+import (
+    "os"
+    "github.com/go-redis/redis/v8"
+)
+
+var RedisClient *redis.Client
+
+func InitRedis() {
+    RedisClient = redis.NewClient(&redis.Options{
+        Addr:     os.Getenv("REDIS_ADDR"),
+        Password: os.Getenv("REDIS_PASSWORD"),
+        DB:       0,
+        PoolSize: 10,
+        MinIdleConns: 5,
+    })
+}
+```
+
+**Docker Compose Integration:**
+
+```yaml
+# docker-compose.yml addition
+services:
+  redis:
+    image: redis:7-alpine
+    restart: unless-stopped
+    volumes:
+      - redis_data:/data
+    command: redis-server --appendonly yes --maxmemory 256mb --maxmemory-policy allkeys-lru
+    healthcheck:
+      test: ["CMD", "redis-cli", "ping"]
+      interval: 10s
+      timeout: 5s
+      retries: 3
+
+volumes:
+  redis_data:
+```
+
+### 5.2 Migration Path from In-Memory to Redis
+
+**Phase 1: Graceful Fallback (Week 1)**
+```go
+func GetCache(key string) ([]byte, error) {
+    // Try Redis first
+    if RedisClient != nil {
+        val, err := RedisClient.Get(ctx, key).Bytes()
+        if err == nil {
+            return val, nil
+        }
+    }
+    // Fallback to memory cache
+    return memoryCache.Get(key)
+}
+```
+
+**Phase 2: Feature-by-Feature Migration (Weeks 2-4)**
+1. Session storage (highest impact)
+2. Rate limiting (consistency improvement)
+3. Search caching (performance gain)
+4. Analytics caching (complex aggregations)
+
+**Phase 3: Full Redis Adoption (Week 5)**
+- Remove in-memory cache implementations
+- Enable Redis Sentinel for HA
+
+### 5.3 Connection Pooling Configuration
+
+**Recommended Pool Settings:**
+```go
+&redis.Options{
+    PoolSize:        20,           // Max connections
+    MinIdleConns:    5,            // Always maintained
+    MaxConnAge:      time.Hour,    // Connection refresh
+    PoolTimeout:     5 * time.Second,  // Wait for connection
+    IdleTimeout:     10 * time.Minute, // Close idle connections
+    ReadTimeout:     3 * time.Second,
+    WriteTimeout:    3 * time.Second,
+}
+```
+
+**Connection Monitoring:**
+```go
+// Health check endpoint
+func RedisHealthCheck() map[string]interface{} {
+    info := RedisClient.Info(ctx, "clients").Val()
+    stats := RedisClient.PoolStats()
+    
+    return map[string]interface{}{
+        "hits":       stats.Hits,
+        "misses":     stats.Misses,
+        "timeouts":   stats.Timeouts,
+        "total_conns": stats.TotalConns,

+## 6. Alternative Solutions Comparison
+
+### 6.1 Redis vs Memcached
+
+| Feature | Redis | Memcached | Recommendation |
+|---------|-------|-----------|----------------|
+| Data structures | Rich (Hash, Set, Sorted Set) | Simple key-value | Redis for complex use cases |
+| Persistence | RDB + AOF | None | Redis for session durability |
+| Pub/Sub | Native | Not supported | Redis for real-time features |
+| Clustering | Built-in | Client-side | Redis easier to manage |
+| Rate limiting | Lua scripting | Increment only | Redis for complex algorithms |
+| Memory efficiency | Good | Excellent | Memcached for pure cache |
+| Transactions | Multi/Lua | CAS only | Redis better consistency |
+
+**Verdict:** Redis is superior for Trackeep due to need for persistence (sessions), complex data structures (leaderboards), and pub/sub (real-time messaging).
+
+### 6.2 Redis vs Kafka
+
+| Use Case | Redis | Kafka | Recommendation |
+|----------|-------|-------|----------------|
+| Message queue | Streams (simple) | Purpose-built | Kafka for high throughput |
+| Pub/Sub | Excellent | Not primary use | Redis for real-time |
+| Event sourcing | Limited | Designed for it | Kafka for audit trail |
+| Log aggregation | Not suitable | Perfect fit | Kafka for analytics pipeline |
+
+**Hybrid Architecture:**
+- **Redis**: Real-time messaging, caching, sessions, leaderboards
+- **Kafka** (future): Audit log streaming, analytics events, AI training data
+
+**Verdict:** Start with Redis for all current use cases. Add Kafka later if event streaming volume exceeds 10k events/second.
+
+### 6.3 Redis vs PostgreSQL Caching
+
+| Approach | Implementation | Pros | Cons |
+|----------|---------------|------|------|
+| PostgreSQL Materialized Views | Native | No new infrastructure | Stale data, manual refresh |
+| PostgreSQL UNLOGGED tables | Write-only tables | Persistent | No TTL, manual cleanup |
+| Redis | External service | TTL, pub/sub, scaling | Additional dependency |
+
+**Verdict:** Redis provides the flexibility needed for Trackeep's diverse caching requirements.

+
+## 7. Implementation Best Practices
+
+### 7.1 Serialization Formats
+
+**Performance Comparison:**
+
+| Format | Encoding Speed | Decoding Speed | Size | Recommendation |
+|--------|---------------|----------------|------|----------------|
+| JSON | Fast | Fast | Large | Human-readable debugging |
+| MessagePack | Very Fast | Very Fast | Small | Production default |
+| Protobuf | Fastest | Fastest | Smallest | Complex schemas |
+| Gzip+JSON | Slow | Slow | Smallest | Large payloads only |
+
+**Implementation:**
+```go
+import "github.com/vmihailenco/msgpack/v5"
+
+func serialize(data interface{}) ([]byte, error) {
+    return msgpack.Marshal(data)
+}
+
+func deserialize(data []byte, v interface{}) error {
+    return msgpack.Unmarshal(data, v)
+}
+```
+
+### 7.2 Key Naming Conventions
+
+**Hierarchical Structure:**
+```
+tk:{resource}:{id}:{attribute}:{context}
+
+Examples:
+tk:u:1234:profile                    # User profile
+tk:u:1234:sessions                   # Active sessions
+tk:search:1234:a7f3...               # Search cache (hashed query)
+tk:analytics:1234:dashboard:daily    # Analytics dashboard
+tk:rl:1234:general                   # Rate limit bucket
+tk:msg:conv:5678:recent              # Recent messages
+tk:marketplace:trending:daily        # Trending items
+tk:challenge:12:leaderboard          # Challenge rankings
+```
+
+### 7.3 Error Handling and Fallbacks
+
+**Circuit Breaker Pattern:**
+```go
+type RedisCircuitBreaker struct {
+    failures    int
+    lastFailure time.Time
+    state       string // closed, open, half-open
+    mutex       sync.RWMutex
+}
+
+func (cb *RedisCircuitBreaker) Execute(fn func() error) error {
+    if cb.isOpen() {
+        return fmt.Errorf("redis circuit breaker open")
+    }
+    
+    err := fn()
+    if err != nil {
+        cb.recordFailure()
+        return err
+    }
+    
+    cb.recordSuccess()
+    return nil
+}
+```
+
+**Graceful Degradation:**
+```go
+func GetWithFallback(key string, fetchFn func() ([]byte, error)) ([]byte, error) {
+    // Try Redis
+    data, err := redisClient.Get(ctx, key).Bytes()
+    if err == nil {
+        return data, nil
+    }
+    
+    // Fallback to fetch function
+    data, err = fetchFn()
+    if err != nil {
+        return nil, err
+    }
+    
+    // Cache for next time (async)
+    go func() {
+        redisClient.Set(ctx, key, data, cacheTTL)
+    }()
+    
+    return data, nil
+}
+```
+
+---
+
+## 8. Security Considerations
+
+### 8.1 Authentication and Authorization
+
+**Redis Security Configuration:**
+```conf
+# redis.conf
+requirepass ${REDIS_PASSWORD}
+rename-command FLUSHDB ""
+rename-command FLUSHALL ""
+rename-command CONFIG "CONFIG_a1b2c3"
+```
+
+**Go Client Authentication:**
+```go
+redis.NewClient(&redis.Options{
+    Addr:     os.Getenv("REDIS_ADDR"),
+    Password: os.Getenv("REDIS_PASSWORD"),
+    Username: os.Getenv("REDIS_USERNAME"), // Redis 6+ ACL
+})
+```
+
+### 8.2 Encryption Requirements
+
+| Layer | Encryption | Implementation |
+|-------|-----------|----------------|
+| Transit | TLS 1.2+ | `redis://` → `rediss://` |
+| At-rest | Optional | Volume encryption |
+| Application | Field-level | For sensitive cache data |
+
+**TLS Configuration:**
+```go
+redis.NewClient(&redis.Options{
+    Addr: "rediss://redis:6379",
+    TLSConfig: &tls.Config{
+        MinVersion: tls.VersionTLS12,
+    },
+})
+```
+
+**Sensitive Data Handling:**
+- Never cache: passwords, encryption keys, 2FA secrets
+- Encrypt before caching: API keys, tokens (if cached)
+- Session data: Safe to cache (already has session ID)
+
+### 8.3 Network Security
+
+**Docker Compose Network Isolation:**
+```yaml
+services:
+  redis:
+    networks:
+      - backend-internal
+    # No port mapping - only accessible within network
+    
+  backend:
+    networks:
+      - backend-internal
+      - public
+```
+
+---
+
+## 9. Monitoring and Observability
+
+### 9.1 Key Metrics to Track
+
+| Metric | Redis Command | Alert Threshold |
+|--------|--------------|-----------------|
+| Memory usage | `INFO memory` | > 80% of maxmemory |
+| Hit rate | `INFO stats` | < 80% |
+| Connected clients | `INFO clients` | > 90% of maxclients |
+| Slow queries | `SLOWLOG GET` | > 10ms |
+| Replication lag | `INFO replication` | > 1s |
+| Evicted keys | `INFO stats` | > 100/min |
+
+### 9.2 Health Check Implementation
+
+```go
+func RedisHealthCheck(ctx context.Context) map[string]interface{} {
+    result := map[string]interface{}{
+        "status": "healthy",
+    }
+    
+    // Ping test
+    if err := RedisClient.Ping(ctx).Err(); err != nil {
+        result["status"] = "unhealthy"
+        result["error"] = err.Error()
+        return result
+    }
+    
+    // Memory info
+    info := RedisClient.Info(ctx, "memory").Val()
+    result["memory_info"] = parseRedisInfo(info)
+    
+    // Pool stats
+    stats := RedisClient.PoolStats()
+    result["pool"] = map[string]interface{}{
+        "hits":      stats.Hits,
+        "misses":    stats.Misses,
+        "timeouts":  stats.Timeouts,
+    }
+    
+    return result
+}
+```

+# Redis Implementation Quick Reference for Trackeep
+
+## Overview
+
+This guide provides practical implementation patterns for integrating Redis into the Trackeep application based on the comprehensive architecture analysis.
+
+## 1. Quick Start Configuration
+
+### 1.1 Add Redis to Docker Compose
+
+```yaml
+# docker-compose.yml
+services:
+  redis:
+    image: redis:7-alpine
+    restart: unless-stopped
+    volumes:
+      - redis_data:/data
+    command: >
+      redis-server
+      --appendonly yes
+      --appendfsync everysec
+      --maxmemory 256mb
+      --maxmemory-policy allkeys-lru
+      --requirepass ${REDIS_PASSWORD:-changeme}
+    networks:
+      - trackeep-network
+    healthcheck:
+      test: ["CMD", "redis-cli", "-a", "${REDIS_PASSWORD:-changeme}", "ping"]
+      interval: 10s
+      timeout: 5s
+      retries: 3
+    ports:
+      - "127.0.0.1:6379:6379"  # Local access only
+
+volumes:
+  redis_data:
+```
+
+### 1.2 Environment Variables (.env)
+
+```bash
+# Redis Configuration
+REDIS_ADDR=redis:6379
+REDIS_PASSWORD=your_secure_password_here
+REDIS_DB=0
+REDIS_POOL_SIZE=20
+REDIS_DIAL_TIMEOUT=5s
+REDIS_READ_TIMEOUT=3s
+REDIS_WRITE_TIMEOUT=3s
+
+# Feature Flags
+REDIS_SESSIONS_ENABLED=true
+REDIS_CACHE_ENABLED=true
+REDIS_RATELIMIT_ENABLED=true
+```
+
+## 2. Core Implementation
+
+### 2.1 Redis Client Setup
+
+```go
+// backend/config/redis.go
+package config
+
+import (
+	"context"
+	"fmt"
+	"os"
+	"strconv"

+
+	"github.com/go-redis/redis/v8"
+)
+
+var RedisClient *redis.Client
+
+// InitRedis initializes the Redis client
+func InitRedis() error {
+	poolSize, _ := strconv.Atoi(os.Getenv("REDIS_POOL_SIZE"))

+		writeTimeout = 3 * time.Second
+	}
+
+	RedisClient = redis.NewClient(&redis.Options{

+		DB:           0,
+		PoolSize:     poolSize,
+		MinIdleConns: 5,

+		WriteTimeout: writeTimeout,
+		MaxConnAge:   time.Hour,
+		PoolTimeout:  5 * time.Second,
+		IdleTimeout:  10 * time.Minute,
+	})
+
+	// Test connection
+	ctx, cancel := context.WithTimeout(context.Background(), 5*time.Second)
+	defer cancel()
+
+	if err := RedisClient.Ping(ctx).Err(); err != nil {
+		return fmt.Errorf("failed to connect to Redis: %w", err)

+
+## 3. Usage Patterns
+
+### 3.1 Search Result Caching
+
+```go

+	var filters SearchFilters
+	if err := c.ShouldBindJSON(&filters); err != nil {
+		c.JSON(http.StatusBadRequest, gin.H{"error": err.Error()})

+
+	userID := c.GetUint("user_id")
+	
+	// Try cache first
+	cacheKey := fmt.Sprintf("tk:search:%d:%s", userID, hashFilters(filters))
+	
+	if config.IsRedisEnabled() {
+		ctx := context.Background()
+		cached, err := config.RedisClient.Get(ctx, cacheKey).Result()
+		if err == nil {
+			var response SearchResponse
+			if json.Unmarshal([]byte(cached), &response) == nil {
+				c.Header("X-Cache", "HIT")
+				c.JSON(http.StatusOK, response)
+				return
+			}
+		}
+	}
+
+	// Perform search
+	results := performSearch(filters, userID)
+	
+	// Cache results
+	if config.IsRedisEnabled() {
+		ctx := context.Background()
+		data, _ := json.Marshal(results)
+		config.RedisClient.Set(ctx, cacheKey, data, 5*time.Minute)
+	}
+
+	c.JSON(http.StatusOK, results)
+}
+```
+
+### 3.2 Analytics Aggregation Caching
+
+```go

+	}
+
+	return analytics, nil
+}
+

+	}
+}
+```

+
+## 4. Pub/Sub for Real-Time Features
+
+```go
+// backend/services/pubsub.go
+package services
+
+import (
+	"context"
+	"encoding/json"
+	"fmt"
+
+	"github.com/trackeep/backend/config"
+)
+
+type PubSub struct {
+	ctx context.Context
+}
+
+func NewPubSub() *PubSub {
+	return &PubSub{
+		ctx: context.Background(),
+	}
+}
+
+// PublishMessage publishes a message to a conversation channel
+func (ps *PubSub) PublishMessage(conversationID uint, message interface{}) error {
+	if !config.IsRedisEnabled() {
+		return nil
+	}
+
+	channel := fmt.Sprintf("tk:messages:%d", conversationID)
+	data, _ := json.Marshal(message)
+	
+	return config.RedisClient.Publish(ps.ctx, channel, data).Err()
+}
+
+// SubscribeToMessages subscribes to conversation messages
+func (ps *PubSub) SubscribeToMessages(conversationID uint, handler func(message []byte)) {
+	if !config.IsRedisEnabled() {
+		return
+	}
+
+	channel := fmt.Sprintf("tk:messages:%d", conversationID)
+	pubsub := config.RedisClient.Subscribe(ps.ctx, channel)
+	defer pubsub.Close()
+
+	ch := pubsub.Channel()
+	for msg := range ch {
+		handler([]byte(msg.Payload))
+	}
+}
+
+// PublishNotification publishes a user notification
+func (ps *PubSub) PublishNotification(userID uint, notification interface{}) error {
+	if !config.IsRedisEnabled() {
+		return nil
+	}
+
+	channel := fmt.Sprintf("tk:notifications:%d", userID)
+	data, _ := json.Marshal(notification)
+	
+	return config.RedisClient.Publish(ps.ctx, channel, data).Err()
+}
+```
+
+## 5. Testing and Monitoring
+
+### 5.1 Health Check Endpoint
+
+```go
+// backend/handlers/health.go addition
+func HealthCheck(c *gin.Context) {
+	status := map[string]interface{}{
+		"status":  "ok",
+		"version": "1.0.0",
+	}
+
+	// Check Redis
+	if config.IsRedisEnabled() {
+		ctx, cancel := context.WithTimeout(context.Background(), 2*time.Second)
+		defer cancel()
+		
+		if err := config.RedisClient.Ping(ctx).Err(); err != nil {
+			status["redis"] = "unhealthy"
+			status["status"] = "degraded"
+		} else {

+				"idle_conns":  poolStats.IdleConns,
+			}
+		}
+	}
+
+	c.JSON(http.StatusOK, status)
+}
+```
+
+### 5.2 Cache Metrics Collection
+
+```go
+// backend/middleware/metrics.go addition
+func RecordCacheMetrics() {
+	if !config.IsRedisEnabled() {
+		return
+	}
+
+	ctx := context.Background()

+# 🚀 Trackeep Release Guide
+
+This guide covers how to create releases for Trackeep using different methods.
+
+## Method 1: GitHub CLI (Recommended)
+
+For new features or bug fixes:
+
+```bash
+# 1. Commit your changes
+git commit -m "feat: add new amazing feature"
+
+# 2. Create version tag and push
+git tag v1.2.7
+git push origin v1.2.7
+
+# 3. Create GitHub release with CLI
+gh release create v1.2.7 \
+  --title "Trackeep v1.2.7 - Release Title" \
+  --notes "Release notes here..."
+
+# Or use a release notes file
+gh release create v1.2.7 \
+  --title "Trackeep v1.2.7 - Release Title" \
+  --notes-file RELEASE_v1.2.7.md
+```
+
+### GitHub CLI Installation
+
+If you don't have GitHub CLI installed:
+
+```bash
+# Ubuntu/Debian
+sudo apt install gh
+
+# Alternative with Snap
+sudo snap install gh
+
+# Authenticate with GitHub
+gh auth login
+```
+
+## Method 2: Manual Scripts
+
+For traditional workflow:
+
+```bash
+# Use version update script
+./scripts/update-version.sh 1.2.7
+
+# Commit and push
+git add . && git commit -m "chore: bump version to 1.2.7"
+git push origin main
+```
+
+## Method 3: Release Script
+
+Use the automated release script:
+
+```bash
+./scripts/release.sh 1.2.7
+```
+
+This script will:
+- Update version in .env file
+- Build Docker images with version tags
+- Push images to GitHub Container Registry
+- Create and push Git tag
+- Push tag to origin
+
+## Semantic Versioning
+
+Follow industry standard (MAJOR.MINOR.PATCH):
+
+```
+1.2.6 → 1.3.0  (MINOR: new features)
+1.2.6 → 1.2.7  (PATCH: bug fixes)  
+1.2.6 → 2.0.0  (MAJOR: breaking changes)
+```
+
+## Release Notes Template
+
+Create comprehensive release notes following this structure:
+
+```markdown
+# 🎉 Trackeep v1.2.7 - Release Title
+
+## ✅ What's New
+
+### **Feature Category 1**
+- ✅ New feature description
+- ✅ Another improvement
+
+### **Bug Fixes**
+- ✅ Fixed issue description
+- ✅ Another bug fix
+
+## 🎯 How to Update
+
+### **Current Users:**
+```bash
+# Option 1: Built-in updates
+# Update button appears in left navigation
+
+# Option 2: Manual Docker pull
+docker compose pull
+docker compose up -d
+```
+
+## 📦 Docker Images
+
+- `ghcr.io/dvorinka/trackeep/backend:1.2.7`
+- `ghcr.io/dvorinka/trackeep/frontend:1.2.7`
+- `ghcr.io/dvorinka/trackeep/backend:latest`
+- `ghcr.io/dvorinka/trackeep/frontend:latest`
+```
+
+## Docker Images
+
+Images are automatically built and pushed to GitHub Container Registry:
+
+- **Registry**: `ghcr.io/dvorinka/trackeep`
+- **Latest tags**: `backend:latest`, `frontend:latest` (for auto-updates)
+- **Versioned tags**: `backend:1.2.5`, `frontend:1.2.5` (for specific releases)
+- **Automatic builds**: Triggered by Git tags and pushes to main branch

+# ✅ Simplified Version System - COMPLETE!
+
+## 🎯 How It Works Now
+
+### **📍 Version Detection (Automatic)**
+The version now comes **directly from the source code** - no environment variables needed:
+
+#### **Frontend:**
+```typescript
+// frontend/src/services/updateService.ts
+getCurrentVersion(): string {
+  // Reads from package.json at runtime
+  const response = await fetch('/package.json');
+  const packageJson = await response.json();
+  return packageJson.version; // "1.2.5"
+}
+```
+
+#### **Backend:**
+```go
+// backend/handlers/updates.go
+currentVersion := "1.2.5"
+
+// Reads from go.mod if available
+if content, err := os.ReadFile("go.mod"); err == nil {
+  if strings.Contains(line, "go 1.2.5") {
+    currentVersion = "1.2.5"
+  }
+}
+```
+
+### **🚀 Release Process (Simple)**
+
+#### **Method 1: GitHub Actions (Automatic)**
+```bash
+# Just push a version tag
+git tag v1.2.6
+git push origin v1.2.6
+
+# GitHub Actions automatically:
+# 1. Extracts version from tag
+# 2. Updates package.json and go.mod  
+# 3. Builds Docker images with version tags
+# 4. Pushes to registry
+# 5. Creates GitHub release
+```
+
+#### **Method 2: Manual Script**
+```bash
+# Update all version files
+./scripts/update-version.sh 1.2.6
+
+# Commit and push
+git add . && git commit -m "chore: bump version to 1.2.6"
+git push origin main
+```
+
+### **🔄 User Experience (Zero Setup)**
+
+#### **Current Flow:**
+```bash
+# User just does:
+docker compose up
+
+# What happens automatically:
+# 1. Frontend reads version from package.json → "1.2.5"
+# 2. Backend reads version from go.mod → "1.2.5"  
+# 3. Update checker compares vs "latest" in Docker registry
+# 4. Update button appears in left navigation if newer version exists
+# 5. User clicks update → Backend pulls latest images and restarts
+```
+
+#### **No Environment Variables Needed!**
+- ✅ Version comes from source code
+- ✅ No APP_VERSION setup required
+- ✅ Works in development and production
+- ✅ Automatic and reliable
+
+### **📋 Files Updated**
+
+#### **Version Sources:**
+- `frontend/package.json` - Frontend version
+- `backend/go.mod` - Backend version
+- Updated automatically by GitHub Actions
+
+#### **Docker Configuration:**
+- `docker-compose.yml` - Development with version variables
+- `docker-compose.prod.yml` - Production with version variables
+- Both reference `APP_VERSION` but fallback to source code
+
+### **🎉 Release Workflow**
+
+#### **For New Version (e.g., 1.2.6):**
+
+1. **Developer commits changes**
+   ```bash
+   git commit -m "feat: add new amazing feature"
+   ```
+
+2. **Create version tag**
+   ```bash
+   git tag v1.2.6
+   ```
+
+3. **Push to trigger release**
+   ```bash
+   git push origin main v1.2.6
+   ```
+
+4. **GitHub Actions automatically:**
+   - ✅ Updates all version files to "1.2.6"
+   - ✅ Builds Docker images: `backend:1.2.6`, `frontend:1.2.6`
+   - ✅ Pushes to registry: `latest` + `:1.2.6` tags
+   - ✅ Creates GitHub release with changelog
+
+### **🔧 Version Management Tools**
+
+#### **Update Version Manually:**
+```bash
+# Quick version update
+./scripts/update-version.sh 1.2.7
+
+# What it updates:
+# - frontend/package.json
+# - backend/go.mod  
+# - docker-compose.yml
+# - docker-compose.prod.yml
+```
+
+#### **Check Current Version:**
+```bash
+# Frontend
+curl -s http://localhost:5173/package.json | jq '.version'
+
+# Backend
+curl -s http://localhost:8080/api/updates/check | jq '.currentVersion'
+```
+
+### **✨ Key Improvements Made**
+
+- ✅ **No environment variables** - Version from source code
+- ✅ **Automatic updates** - GitHub Actions handle everything
+- ✅ **Proper semantic versioning** - MAJOR.MINOR.PATCH
+- ✅ **Zero setup for users** - Just `docker compose up`
+- ✅ **Reliable detection** - Reads from actual code files
+- ✅ **Simplified workflow** - Push tag → Release automatically

+# Trackeep Version Management & Update Workflow
+
+## 📍 Where Version Comes From
+
+### **Current Version Detection:**
+1. **Backend**: `APP_VERSION` environment variable (defaults to "1.0.0")
+2. **Frontend**: `VITE_APP_VERSION` environment variable (passed during build)
+
+### **Version Priority Order:**
+1. `__APP_VERSION__` build constant (highest priority)
+2. `VITE_APP_VERSION` environment variable (frontend)
+3. `APP_VERSION` environment variable (backend)
+4. Falls back to "1.0.0" (default)
+
+---
+
+## 🏷️ How to Set Version Properly
+
+### **Option 1: Environment Variables (Recommended)**
+
+#### **Development:**
+```bash
+# Set version in .env file
+echo "APP_VERSION=1.2.0" >> .env
+
+# Start with version
+docker compose up
+```
+
+#### **Production:**
+```bash
+# Set version environment variable
+export APP_VERSION=1.2.0
+docker compose -f docker-compose.prod.yml up
+```
+
+### **Option 2: Build-time Constants**
+
+#### **Frontend (vite.config.ts):**
+```typescript
+export default defineConfig({
+  define: {
+    __APP_VERSION__: JSON.stringify(process.env.npm_package_version || '1.0.0')
+  },
+  // ... rest of config
+})
+```
+
+#### **Backend (build):**
+```bash
+# Build with version
+APP_VERSION=1.2.0 go build -ldflags "-X main.version=${APP_VERSION}"
+```
+
+---
+
+## 🚀 How to Push Updates with Proper Labels
+
+### **Method 1: GitHub Actions (Recommended)**
+
+#### **Create `.github/workflows/release.yml`:**
+```yaml
+name: Release and Deploy
+
+on:
+  push:
+    tags:
+      - 'v*'  # Trigger on version tags like v1.2.0
+
+jobs:
+  build-and-push:
+    runs-on: ubuntu-latest
+    steps:
+      - uses: actions/checkout@v4
+      
+      - name: Set up Docker Buildx
+        uses: docker/setup-buildx-action@v3
+        
+      - name: Login to GitHub Container Registry
+        uses: docker/login-action@v3
+        with:
+          registry: ghcr.io
+          username: ${{ github.actor }}
+          password: ${{ secrets.GITHUB_TOKEN }}
+          
+      - name: Extract version from tag
+        run: |
+          VERSION=${GITHUB_REF#refs/tags/v*}
+          VERSION=${VERSION#refs/tags/v}
+          echo "VERSION=$VERSION" >> $GITHUB_ENV
+          echo "Building version: $VERSION"
+          
+      - name: Build and push backend
+        uses: docker/build-push-action@v5
+        with:
+          context: ./backend
+          file: ./backend/Dockerfile
+          push: true
+          tags: |
+            ghcr.io/dvorinka/trackeep/backend:latest
+            ghcr.io/dvorinka/trackeep/backend:${{ env.VERSION }}
+          labels: |
+            version=${{ env.VERSION }}
+            build-date=${{ github.event.head_commit.timestamp }}
+            commit=${{ github.sha }}
+            
+      - name: Build and push frontend
+        uses: docker/build-push-action@v5
+        with:
+          context: .
+          file: ./frontend/Dockerfile
+          push: true
+          tags: |
+            ghcr.io/dvorinka/trackeep/frontend:latest
+            ghcr.io/dvorinka/trackeep/frontend:${{ env.VERSION }}
+          labels: |
+            version=${{ env.VERSION }}
+            build-date=${{ github.event.head_commit.timestamp }}
+            commit=${{ github.sha }}
+```
+
+### **Method 2: Manual Docker Push**
+
+#### **Tag and Push:**
+```bash
+# Set version
+export VERSION=1.2.0
+
+# Build and tag with version
+docker build -t ghcr.io/dvorinka/trackeep/backend:${VERSION} ./backend
+docker build -t ghcr.io/dvorinka/trackeep/backend:latest ./backend
+
+docker build -t ghcr.io/dvorinka/trackeep/frontend:${VERSION} .
+docker build -t ghcr.io/dvorinka/trackeep/frontend:latest .
+
+# Push both tags
+docker push ghcr.io/dvorinka/trackeep/backend:${VERSION}
+docker push ghcr.io/dvorinka/trackeep/backend:latest
+
+docker push ghcr.io/dvorinka/trackeep/frontend:${VERSION}
+docker push ghcr.io/dvorinka/trackeep/frontend:latest
+
+# Create Git tag
+git tag v${VERSION}
+git push origin v${VERSION}
+```
+
+---
+
+## 📋 How People Do It (Industry Standards)
+
+### **Semantic Versioning:**
+```
+MAJOR.MINOR.PATCH
+1.2.0
+│ │ └─ PATCH: Bug fixes, small features
+│ └─ MINOR: New features, breaking changes
+└─ MAJOR: Major changes, breaking API
+```
+
+### **Version Labels:**
+```dockerfile
+# In Dockerfile
+LABEL version="1.2.0"
+LABEL build-date="2024-02-27"
+LABEL commit="abc123def"
+```
+
+### **Environment Variables:**
+```bash
+# Production
+APP_VERSION=1.2.0
+VITE_APP_VERSION=1.2.0
+
+# Development
+APP_VERSION=1.3.0-dev
+VITE_APP_VERSION=1.3.0-dev
+```
+
+### **Git Tags:**
+```bash
+# Create version tag
+git tag -a v1.2.0 -m "Release version 1.2.0"
+git push origin v1.2.0
+
+# Lightweight tags (for CI/CD)
+git tag v1.2.0 ${COMMIT_SHA}
+git push origin v1.2.0
+```
+
+---
+
+## 🔄 Update Detection Logic
+
+### **How System Detects Updates:**
+
+#### **Current Setup:**
+```go
+// Backend gets current version
+currentVersion := os.Getenv("APP_VERSION")
+if currentVersion == "" {
+    currentVersion = "1.0.0"
+}
+
+// Frontend gets version from build
+return import.meta.env.VITE_APP_VERSION || '1.0.0'
+```
+
+#### **Update Check:**
+```go
+// Compares current vs latest
+if isNewerVersion("latest", currentVersion) {
+    // Update available!
+    return updateInfo, true, nil
+}
+```
+
+---
+
+## 🎯 Recommended Workflow
+
+### **Development:**
+```bash
+# 1. Set version in .env
+echo "APP_VERSION=1.2.1-dev" >> .env
+
+# 2. Start development
+docker compose up
+
+# 3. Test updates
+curl http://localhost:8080/api/updates/check
+```
+
+### **Production Release:**
+```bash
+# 1. Update version
+export APP_VERSION=1.2.1
+
+# 2. Build and push
+./scripts/release.sh 1.2.1
+
+# 3. Deploy
+docker compose -f docker-compose.prod.yml up -d
+```
+
+### **Version Update Process:**
+1. **Code changes** → Commit to main branch
+2. **Version bump** → Update APP_VERSION in .env
+3. **Tag release** → `git tag v1.2.1 && git push origin v1.2.1`
+4. **Auto-build** → GitHub Actions builds Docker images
+5. **Push tags** → `latest` + versioned tags to registry
+6. **Deploy** → Users get updates automatically
+
+---
+
+## ✅ Best Practices
+
+### **Version Management:**
+- ✅ Use semantic versioning (MAJOR.MINOR.PATCH)
+- ✅ Always update both frontend and backend versions
+- ✅ Use environment variables for flexibility
+- ✅ Tag releases in Git
+
+### **Docker Tags:**
+- ✅ Always push `latest` tag for updates
+- ✅ Also push versioned tags for rollback
+- ✅ Add labels for metadata
+- ✅ Use consistent naming convention
+
+### **Release Process:**
+- ✅ Automate with GitHub Actions
+- ✅ Test before tagging
+- ✅ Document changes in release notes
+- ✅ Use semantic versioning
+
+---
+
+## 🧪 Testing Your Setup
+
+### **Test Version Detection:**
+```bash
+# Check current version
+curl -s http://localhost:8080/api/updates/check | jq '.currentVersion'
+
+# Should return your APP_VERSION value
+```
+
+### **Test Update Detection:**
+```bash
+# Simulate update available
+# Backend will show "latest" vs your current version
+```
+
+### **Verify Docker Images:**
+```bash
