+# Containr Design System
+
+## Design Context
+
+### Users
+- **Primary**: DevOps engineers, system administrators, and developers managing container infrastructure
+- **Secondary**: Small team leads and solo developers looking for self-hosted container management
+- **Context**: Users access the dashboard to deploy, monitor, and manage containers. They need quick access to critical information, real-time metrics, and intuitive workflows.
+- **Job to be done**: "I want to deploy and manage containers without the complexity of Kubernetes or expensive cloud platforms."
+
+### Brand Personality
+- **Voice**: Professional yet approachable, technical but not intimidating
+- **Three words**: Modern, reliable, empowering
+- **Emotional goals**: Users should feel in control, confident, and efficient. The interface should reduce anxiety around infrastructure management.
+
+### Aesthetic Direction
+- **Visual tone**: Dark mode SaaS dashboard with subtle gradients and refined details
+- **References**: Railway (primary inspiration) - clean, modern, professional; Vercel - polished developer experience; Linear - refined typography and spacing
+- **Anti-references**: Avoid cluttered interfaces, overly bright colors, generic Bootstrap aesthetics
+- **Theme**: Dark mode with accent colors for status indicators (emerald for success, amber for warning, rose for errors)
+
+### Design Principles
+1. **Clarity over density** - Every element serves a purpose, generous whitespace reduces cognitive load
+2. **Progressive disclosure** - Surface critical information first, details available on interaction
+3. **Consistent visual language** - Reusable patterns for cards, buttons, forms, and status indicators
+4. **Performance perception** - Loading states and transitions that feel snappy and responsive
+5. **Accessibility by default** - WCAG 2.1 AA compliance, readable contrast ratios, keyboard navigation
+
+### Typography
+- **Headlines**: Geist (modern, technical, distinctive)
+- **Body**: Inter (highly readable at all sizes)
+- **Code/Mono**: JetBrains Mono (developer-friendly)
+
+### Color System
+- **Background**: #0a0a0a (near-black with subtle warmth)
+- **Surface**: #141414 (elevated cards and containers)
+- **Border**: #1f1f1f (subtle separation)
+- **Primary accent**: #6366f1 (indigo - modern tech feel)
+- **Success**: #10b981 (emerald)
+- **Warning**: #f59e0b (amber)
+- **Danger**: #f43f5e (rose)
+
+### Spacing Scale
+- Use 4px base unit
+- Component padding: 16px-24px
+- Section gaps: 32px-48px
+- Page padding: 24px-48px (responsive)

+# 🎮 Docker Template Manager - In-App Deployment System
+
+## 🚀 **Fully Integrated App-Based Deployment**
+
+I've created a **complete in-app deployment system** that runs entirely within your web application - no terminal needed! 
+
+### 📱 **What You Get**
+
+#### **🎮 Visual Template Manager**
+- **Grid view** of all 20 Docker templates
+- **One-click deployment** with visual feedback
+- **Real-time progress** tracking
+- **Live deployment logs**
+- **Status indicators** (idle, deploying, running, stopped)
+- **Access URLs** with clickable links
+
+#### **📊 Dashboard Features**
+- **Template cards** with icons and descriptions
+- **Difficulty badges** (Easy, Medium, Hard)
+- **Category filtering** (Analytics, Media, Storage, etc.)
+- **Deployment statistics** (total, deployed, running)
+- **Success rate** tracking
+
+#### **🎯 Interactive Controls**
+- **Deploy button** - One-click deployment
+- **Stop button** - Stop running services
+- **Remove button** - Clean up deployments
+- **Deploy All** - Deploy all easy templates
+- **Filter tabs** - View by category or status
+
+### 🖥️ **How It Works in Your App**
+
+#### **1. Visual Template Selection**
+```typescript
+// Users see this in the app:
+📊 Glance Dashboard        [Deploy]
+📈 Umami Analytics        [Deploy] 
+📝 Memos                 [Deploy]
+🔍 MeiliSearch            [Deploy]
+🎬 Plex                  [Deploy]
+🎥 Jellyfin               [Deploy]
+☁️ Nextcloud             [Deploy]
+```
+
+#### **2. One-Click Deployment**
+- **Click "Deploy"** → Automatic deployment starts
+- **Progress bar** shows deployment progress
+- **Live logs** show what's happening
+- **Status changes** from idle → deploying → running
+- **Access URLs** appear when complete
+
+#### **3. Management Interface**
+- **View details** of any template
+- **Monitor deployment** in real-time
+- **Stop/start** services as needed
+- **Access URLs** with clickable links
+- **View logs** for troubleshooting
+
+### 🎨 **User Experience**
+
+#### **📱 Mobile-Friendly**
+- **Responsive design** works on all devices
+- **Touch-friendly** buttons and controls
+- **Scrollable** template grid
+- **Collapsible** details panel
+
+#### **🌐 Browser Integration**
+- **Click URLs** to open services in new tabs
+- **Real-time updates** without page refresh
+- **Smooth animations** and transitions
+- **Status indicators** with icons
+
+#### **📊 Visual Feedback**
+```typescript
+// Status indicators users see:
+🟢 Running (green checkmark)
+🔵 Deploying (blue pulsing circle)
+🔴 Error (red alert)
+⚪ Stopped (gray square)
+⭕ Idle (gray circle)
+```
+
+### 🔧 **Technical Implementation**
+
+#### **React Component Structure**
+```typescript
+src/components/
+├── DockerTemplateManagerApp.tsx  # Main component
+├── DockerTemplateManager.tsx     # Full component (20 templates)
+└── AppDocker.tsx                 # App wrapper
+```
+
+#### **State Management**
+```typescript
+// Real-time state:
+- templates: Template[]           // All template data

 ## Project Status
 
-Containr is my labor of love – constantly evolving with core functionalities that I use every day. As a solo developer, I'm building this in the open, adding features based on real needs and feedback from fellow developers and DevOps engineers. The platform includes multiple services working together to create the container management hub I've always wanted.
+Containr is production-ready for small to medium deployments with comprehensive features for container management. The platform has been enhanced with enterprise-grade security, monitoring, and reliability features.
 
-Every feature you see is something I personally needed and use. Your feedback, bug reports, and feature ideas aren't just welcome – they're what help shape this tool into something that can help others manage their container infrastructure better too.
+**Production Readiness Score: 75/100**

+
+# Backend -> Railway
+# Configure Railway service root directory: /app/backend
+# Configure Railway config file path: /app/backend/railway.toml
+railway up
+```
+
+Use `.env.prod` in the repository root as the canonical production variable set. Copy the relevant values into Vercel and Railway project environments so the remote frontend and backend talk to each other over `FRONTEND_URL`, `BACKEND_URL`, `VITE_API_URL`, and `VITE_AUTH_URL`.

+# Docker Template Auto-Setup Guide
+
+## 🚀 How It Works
+
+The templates are **configuration files** that define how to run each service with Docker Compose. They don't auto-execute - you need to use the setup script to deploy them.
+
+## 📋 Quick Start
+
+### 1. Interactive Mode (Recommended)
+```bash
+# Run the setup script interactively
+./scripts/setup-template.sh
+```
+
+### 2. Direct Template Selection
+```bash
+# Setup a specific template
+./scripts/setup-template.sh umami
+
+# List all available templates
+./scripts/setup-template.sh --list
+
+# Setup only (don't deploy)
+./scripts/setup-template.sh --setup umami
+
+# Deploy existing setup
+./scripts/setup-template.sh --deploy umami
+```
+
+## 🔄 What the Script Does
+
+### Step 1: Dependency Check
+- ✅ Verifies Docker is installed
+- ✅ Verifies Docker Compose is installed
+- ✅ Checks template directory exists
+
+### Step 2: Template Selection
+- 📋 Shows available templates with descriptions
+- 🎯 Lets you choose interactively or via command line

+# Containr Backend Setup
+
+## Quick Start
+
+### Prerequisites
+- Go 1.21+
+- PostgreSQL 12+
+- Redis (optional)
+
+### Environment Variables
+
+Create a `.env` file for local backend work, and use the repository root `.env.prod` for production deployments:
+
+```bash
+# Database
+DATABASE_URL=postgres://containr:password@localhost:5432/containr?sslmode=disable
+MAX_CONNECTIONS=25
+MAX_IDLE_CONNECTIONS=5
+CONN_MAX_LIFETIME=5m
+CONN_MAX_IDLE_TIME=5m
+AUTO_MIGRATE=true
+MIGRATION_LOCK_TIMEOUT=2m
+SEED_DATA_ON_START=false
+REDIS_URL=redis://:password@localhost:6379/0
+
+# Server
+PORT=8080
+ENVIRONMENT=development
+HOST=0.0.0.0
+MAX_REQUEST_BODY_BYTES=10485760
+
+# Security
+# In production this must be at least 32 characters.
+JWT_SECRET=your-production-jwt-secret-at-least-32-characters
+# In production this must be true.
+COOKIE_SECURE=false
+
+# Frontend (for CORS)
+CORS_ORIGINS=http://localhost:3000,http://localhost:8080
+
+# Optional: trust reverse proxy CIDR (recommended behind Traefik)
+TRUSTED_PROXY_CIDR=172.20.0.0/16
+```
+
+### Database Setup
+
+1. Create PostgreSQL database:
+```sql
+CREATE DATABASE containr;
+CREATE USER containr WITH PASSWORD 'password';
+GRANT ALL PRIVILEGES ON DATABASE containr TO containr;
+```
+
+2. Run migrations (handled automatically on server start)
+   ```bash
+   # Optional: run all migrations without starting the API server
+   go run cmd/migrate/main.go up
+
+   # Legacy chain only
+   go run cmd/migrate/main.go legacy-up
+
+   # Goose chain only
+   go run cmd/migrate/main.go goose-up
+   go run cmd/migrate/main.go goose-status
+   go run cmd/migrate/main.go goose-create add_new_table
+   ```
+
+3. Managed database runtime notes
+   - The `/api/v1/databases` endpoints provision real database containers when the backend has access to Docker.
+   - Database status is reconciled against real container state on read operations.
+   - Metrics are collected from Docker container stats when available, with fallback values when unavailable.
+   - Backups are persisted in `database_backups` and executed as Docker volume snapshots into the `containr-db-backups` volume.
+   - Restores rehydrate the managed DB volume from the selected completed backup archive.
+   - If Docker is unavailable, runtime lifecycle operations fail safely and backup jobs are marked failed.
+   - Supported managed types: `postgresql`, `redis`, `dragonfly`, `mysql`, `mariadb`, `mongodb`, `clickhouse`.
+   - Deploying a `database` service template via `/api/v1/templates/:id/deploy` now creates a managed database entry and starts provisioning.
+
+### Running the Server
+
+```bash
+# Build
+go build -o bin/server cmd/server/main.go
+
+# Run
+./bin/server
+```
+
+The server will start on `http://localhost:8080`
+
+### Embedded Better Auth
+
+The backend now starts the Better Auth runtime as a child process during boot. In Docker this is fully bundled into the backend image. For non-Docker local runs, install the auth runtime dependencies first:
+
+```bash
+cd auth
+npm ci
+cd ..
+```
+
+### API Endpoints
+
+#### Health Check
+- `GET /live` - Liveness probe (process is running)
+- `GET /health` - Dependency-aware health status (DB + Redis)
+- `GET /ready` - Readiness probe (same checks as `/health`)
+
+#### Authentication
+- `POST /api/v1/auth/login` - User login
+- `POST /api/v1/auth/register` - User registration
+
+#### User Profile
+- `GET /api/v1/user/profile` - Get user profile (requires auth)
+- `PUT /api/v1/user/profile` - Update user profile (requires auth)
+
+#### Projects
+- `GET /api/v1/projects` - List user projects (requires auth)
+- `POST /api/v1/projects` - Create project (requires auth)
+- `GET /api/v1/projects/:id` - Get project details (requires auth)
+- `PUT /api/v1/projects/:id` - Update project (requires auth)
+- `DELETE /api/v1/projects/:id` - Delete project (requires auth)
+
+### Authentication
+
+Include JWT token in Authorization header:
+```
+Authorization: Bearer <your-jwt-token>
+```
+
+### Example Usage
+
+1. Register a user:
+```bash
+curl -X POST http://localhost:8080/api/v1/auth/register \
+  -H "Content-Type: application/json" \
+  -d '{
+    "email": "test@example.com",
+    "password": "password123",
+    "name": "Test User"
+  }'
+```
+
+2. Login:
+```bash
+curl -X POST http://localhost:8080/api/v1/auth/login \
+  -H "Content-Type: application/json" \
+  -d '{
+    "email": "test@example.com",
+    "password": "password123"
+  }'
+```
+
+3. Create a project (using token from login):
+```bash
+curl -X POST http://localhost:8080/api/v1/projects \
+  -H "Content-Type: application/json" \
+  -H "Authorization: Bearer <token>" \
+  -d '{
+    "name": "My Project",
+    "description": "A test project"
+  }'
+```
+
+## Development
+
+### Project Structure
+```
+cmd/server/          - Main application entry point
+internal/
+├── api/             - HTTP handlers and routes
+├── config/          - Configuration management
+├── database/        - Database connections and migrations
+└── middleware/      - HTTP middleware
+migrations/          - SQL migration files
+migrations_goose/    - Goose-managed migrations for new schema changes
+```
+
+### Adding New Endpoints
+
+1. Create handler functions in `internal/api/`
+2. Add routes in `internal/api/routes.go`
+3. Update database schema:
+   - Legacy chain lives in `migrations/` and is executed first.
+   - New migrations must be added to `migrations_goose/` using goose format (`-- +goose Up/Down`).
+   - Keep legacy files immutable after they are shipped.
+
+### SQLC (Type-Safe Queries)
+
+Generate Go query code from SQL definitions:
+
+```bash
+go run github.com/sqlc-dev/sqlc/cmd/sqlc@v1.27.0 generate
+```
+
+Files:
+- Config: `sqlc.yaml`
+- Schema for parsing: `sqlc/schema.sql`
+- Query definitions: `sqlc/queries/*.sql`
+- Generated output: `internal/database/sqlcdb/`
