+}
+```
+
+### Python Full Example
+
+```python
+import requests
+from typing import List, Dict, Optional
+
+class CzechClubsAPI:
+    def __init__(self, base_url: str = "http://localhost:8080"):
+        self.base_url = base_url
+    
+    def search_clubs(self, query: str) -> List[Dict]:
+        response = requests.get(f"{self.base_url}/clubs/search?q={query}")
+        response.raise_for_status()
+        return response.json()
+    
+    def get_club(self, club_id: str) -> Dict:
+        response = requests.get(f"{self.base_url}/clubs/{club_id}")
+        response.raise_for_status()
+        return response.json()
+    
+    def upload_logo(self, club_id: str, file_path: str) -> Dict:
+        with open(file_path, 'rb') as f:
+            files = {'file': f}
+            response = requests.post(
+                f"{self.base_url}/logos/{club_id}",
+                files=files
+            )
+        response.raise_for_status()
+        return response.json()
+    
+    def get_logo_url(self, club_id: str) -> str:
+        return f"{self.base_url}/logos/{club_id}"
+    
+    def get_logo_metadata(self, club_id: str) -> Dict:
+        response = requests.get(f"{self.base_url}/logos/{club_id}/json")
+        response.raise_for_status()
+        return response.json()
+    
+    def download_logo(self, club_id: str, output_path: str):
+        response = requests.get(self.get_logo_url(club_id))
+        response.raise_for_status()
+        
+        with open(output_path, 'wb') as f:
+            f.write(response.content)
+
+# Usage
+api = CzechClubsAPI()
+
+# Search for clubs
+clubs = api.search_clubs("sparta")
+print(f"Found {len(clubs)} clubs")
+
+# Get first club
+sparta = clubs[0]
+print(f"Club: {sparta['name']}")
+
+# Upload logo
+result = api.upload_logo(sparta['id'], 'sparta.svg')
+print(f"Upload: {result['message']}")
+
+# Download logo
+api.download_logo(sparta['id'], 'downloaded_sparta.svg')
+print("Logo downloaded!")
+
+# Get metadata
+metadata = api.get_logo_metadata(sparta['id'])
+print(f"File size: {metadata['file_size']} bytes")
+```
+
+## 🌐 CORS Configuration
+
+The API has CORS enabled. You can make requests from any origin in development.
+
+For production, configure allowed origins in `backend/main.go`:
+
+```go
+r.Use(cors.New(cors.Config{
+    AllowOrigins: []string{"https://yourdomain.com"},
+    AllowMethods: []string{"GET", "POST", "PUT", "DELETE"},
+}))
+```
+
+## 🔒 Error Handling
+
+### Common HTTP Status Codes
+
+| Code | Meaning | Example |
+|------|---------|---------|
+| 200 | Success | Request completed |
+| 400 | Bad Request | Invalid UUID format |
+| 404 | Not Found | Logo doesn't exist |
+| 500 | Server Error | Database issue |
+
+### Error Response Format
+
+```json
+{
+  "error": "error message description"
+}
+```
+
+### JavaScript Error Handling
+
+```javascript
+async function safeGetLogo(clubId) {
+  try {
+    const response = await fetch(`http://localhost:8080/logos/${clubId}/json`)
+    
+    if (!response.ok) {
+      const error = await response.json()
+      throw new Error(error.error || 'Request failed')
+    }
+    
+    return await response.json()
+  } catch (error) {
+    console.error('Failed to get logo:', error.message)
+    return null
+  }
+}
+```

+## 📏 Coding Standards
+
+### Go (Backend)
+
+- Follow [Effective Go](https://golang.org/doc/effective_go)
+- Use `gofmt` for formatting
+- Use meaningful variable names
+- Add comments for exported functions
+- Handle errors properly
+
+**Example:**
+```go
+// GetClub retrieves a club by its UUID from the FAČR API
+func (c *FACRClient) GetClub(id string) (*Club, error) {
+    if id == "" {
+        return nil, fmt.Errorf("club ID is required")
+    }
+    
+    // Implementation...
+}
+```
+
+### JavaScript (Frontend)
+
+- Use ES6+ features
+- Use `const` by default, `let` when reassignment needed
+- Use async/await for asynchronous operations
+- Add JSDoc comments for functions
+- Keep functions small and focused
+
+**Example:**
+```javascript
+/**
+ * Search for clubs by name
+ * @param {string} query - Search query
+ * @returns {Promise<Array>} Array of club objects
+ */
+async function searchClubs(query) {
+    const response = await fetch(`${API_BASE_URL}/clubs/search?q=${query}`)
+    return await response.json()
+}
+```
+
+### CSS
+
+- Use Tailwind utility classes
+- Add custom CSS only when necessary
+- Follow BEM naming for custom classes
+- Keep styles modular and reusable
+
+### General
+
+- Write self-documenting code
+- Add comments for complex logic
+- Keep functions under 50 lines

+4. **Deploy** automatically on git push
+
+## 🔧 Environment Variables
+
+### Backend (.env)
+```bash
+# Server
+PORT=8080
+
+# Database
+DB_PATH=/data/db.sqlite
+
+# Storage
+LOGOS_PATH=/data/logos
+
+# CORS (optional - restrict origins in production)
+ALLOWED_ORIGINS=https://yourdomain.com
+
+# Optional: Cloud Storage
+# AWS_S3_BUCKET=your-bucket
+# AWS_REGION=us-east-1
+# AWS_ACCESS_KEY_ID=xxx
+# AWS_SECRET_ACCESS_KEY=xxx
+```
+
+### Frontend
+Update `frontend/src/main.js` before building:
+```javascript
+const API_BASE_URL = 'https://api.yourdomain.com'
+```
+
+Or use environment variables with Vite:
+```javascript
+const API_BASE_URL = import.meta.env.VITE_API_URL || 'http://localhost:8080'
+```
+
+`.env.production`:
+```
+VITE_API_URL=https://api.yourdomain.com
+```
+
+## 💾 Database Migration
+
+### SQLite to PostgreSQL (Future)
+
+1. **Export data from SQLite:**
+```bash
+sqlite3 db.sqlite .dump > dump.sql
+```
+
+2. **Import to PostgreSQL:**
+```bash
+psql -U username -d dbname -f dump.sql
+```
+
+3. **Update backend code** to use PostgreSQL driver
+
+## 📦 Backup Strategy
+
+### Automated Backups
+
+Create backup script (`backup.sh`):
+```bash
+#!/bin/bash
+DATE=$(date +%Y%m%d_%H%M%S)
+BACKUP_DIR="/backups"
+
+# Backup database
+cp ./data/db.sqlite $BACKUP_DIR/db_$DATE.sqlite
+
+# Backup logos
+tar -czf $BACKUP_DIR/logos_$DATE.tar.gz ./data/logos/
+
+# Keep only last 30 days
+find $BACKUP_DIR -type f -mtime +30 -delete
+
+echo "Backup completed: $DATE"
+```
+
+### Cron job:
+```bash
+crontab -e
+# Add: Run daily at 2 AM
+0 2 * * * /path/to/backup.sh
+```
+
+### Cloud Storage Backup
+```bash
+# Sync to S3
+aws s3 sync ./data/logos s3://your-bucket/logos/ --delete
+
+# Sync to Google Cloud Storage
+gsutil rsync -r ./data/logos gs://your-bucket/logos/
+```
+
+## 📊 Monitoring
+
+### Health Checks
+
+The API provides a health endpoint:
+```bash
+curl http://localhost:8080/health
+```
+
+### Docker Health Check
+
+Add to `docker-compose.yml`:
+```yaml
+services:
+  backend:
+    healthcheck:
+      test: ["CMD", "wget", "--quiet", "--tries=1", "--spider", "http://localhost:8080/health"]
+      interval: 30s
+      timeout: 10s
+      retries: 3
+```
+
+### Logging
+
+**View logs:**
+```bash
+# Docker Compose
+docker-compose logs -f
+
+# Individual services
+docker logs -f czech-backend
+docker logs -f czech-frontend
+```
+
+**Centralized logging (ELK Stack):**
+```yaml
+# Add to docker-compose.yml
+logging:
+  driver: "json-file"
+  options:
+    max-size: "10m"
+    max-file: "3"
+```
+
+### Uptime Monitoring
+
+Use services like:
+- **UptimeRobot** - Free uptime monitoring
+- **Pingdom** - Advanced monitoring
+- **StatusCake** - Multi-location checks
+
+Configure monitors for:
+- `https://yourdomain.com` (Frontend)

+
+### Updated Files
+- `backend/main.go` - Added logo subdirectories, list endpoint
+- `backend/go.mod` - Added image processing dependencies
+- `backend/facr_client.go` - Added Website field to Club struct
+- `frontend/vite.config.js` - Multi-page build support
+- `frontend/src/main.js` - Moved to home.js
+
+---
+
+## 🔧 Setup Requirements
+
+### Backend Dependencies
+```bash
+# Go modules (already configured)
+go mod tidy
+
+# Optional: Image conversion tools
+# Install ONE of these for SVG → PNG conversion:
+
+# Option 1: ImageMagick (recommended)
+# Windows: choco install imagemagick
+# Mac: brew install imagemagick
+# Linux: sudo apt install imagemagick
+
+# Option 2: Inkscape
+# Windows: choco install inkscape
+# Mac: brew install inkscape
+# Linux: sudo apt install inkscape
+```
+
+**Note:** SVG conversion is optional. If neither tool is installed, SVG files will still be stored, just not auto-converted to PNG.
+
+### Frontend Dependencies
+```bash
+cd frontend
+npm install  # Already configured, no new deps
+```
+
+---
+
+## 🚀 How to Use New Features
+
+### 1. Browse Logos (Home Page)
+```bash
+# Start services
+docker-compose up
+
+# Visit
+http://localhost:3000/
+
+# Features available:
+- View all uploaded logos
+- Search/filter logos
+- Click to copy logo URL
+```
+
+### 2. Upload Logos (Admin Page)
+```bash
+# Visit
+http://localhost:3000/admin.html
+
+# Steps:
+1. Search for a club
+2. Click "Select" on search result
+3. Fill in club details (name is REQUIRED)
+4. Optionally search for club website
+5. Upload SVG or PNG logo
+6. Submit (both formats will be available)
+```
+
+### 3. Use API with Format Selection
+```bash
+# Get logo (PNG by default)
+curl http://localhost:8080/logos/{uuid}
+
+# Get specific format
+curl http://localhost:8080/logos/{uuid}?format=svg
+curl http://localhost:8080/logos/{uuid}?format=png
+
+# List all logos
+curl http://localhost:8080/logos
+
+# Get logo metadata
+curl http://localhost:8080/logos/{uuid}/json
+```
+
+### 4. Upload via GitHub PR
+```markdown
+1. Create PR with logo file named {uuid}.svg or {uuid}.png
+2. Use PR template to provide:
+   - Club Name: AC Sparta Praha
+   - Club ID: 22222222-3333-4444-5555-666666666666
+3. GitHub Actions will validate
+4. Auto-approved if valid, auto-rejected if invalid
+```

+
+## 📊 API Changes
+
+### New Endpoints
+| Method | Endpoint | Description |
+|--------|----------|-------------|
+| GET | `/logos` | **NEW** - List all logos |
+
+### Enhanced Endpoints
+| Method | Endpoint | Changes |
+|--------|----------|---------|
+| GET | `/logos/:id` | Now supports `?format=svg` or `?format=png` |
+| GET | `/logos/:id/json` | Returns has_svg, has_png, both URLs |
+| POST | `/logos/:id` | Requires club_name, stores both formats |
+
+### Response Changes
+
+**GET /logos/:id/json** - New Response:
+```json
+{
+  "id": "uuid",
+  "club_name": "AC Sparta Praha",
+  "club_city": "Praha",
+  "club_type": "football",
+  "club_website": "https://www.sparta.cz",  // NEW
+  "has_svg": true,                           // NEW
+  "has_png": true,                           // NEW
+  "primary_format": "png",                   // NEW
+  "logo_url": "http://localhost:8080/logos/uuid?format=png",
+  "logo_url_svg": "http://localhost:8080/logos/uuid?format=svg",  // NEW
+  "logo_url_png": "http://localhost:8080/logos/uuid?format=png",  // NEW
+  "file_size_svg": 12345,                    // NEW
+  "file_size_png": 8192,                     // NEW
+  "created_at": "2024-01-01T12:00:00Z",
+  "updated_at": "2024-01-01T12:00:00Z"
+}
+```
+
+**POST /logos/:id** - New Required Field:
+```bash
+curl -X POST http://localhost:8080/logos/{uuid} \
+  -F "file=@logo.svg" \
+  -F "club_name=AC Sparta Praha" \    # NOW REQUIRED
+  -F "club_city=Praha" \
+  -F "club_type=football" \
+  -F "club_website=https://sparta.cz" # NEW FIELD
+```
+
+---
+
+## ⚠️ Breaking Changes
+
+### 1. **club_name is now REQUIRED**
+- **Old:** Could upload without club name
+- **New:** Upload rejected without club_name
+- **Migration:** Existing logos without names need manual update
+
+### 2. **Logo file paths changed**
+- **Old:** `./logos/{uuid}.svg`
+- **New:** `./logos/svg/{uuid}.svg` and `./logos/png/{uuid}.png`
+- **Migration:** Run migration script or move files manually
+
+### 3. **Database schema updated**
+- **Old:** Single file_extension and file_size columns
+- **New:** Separate columns for SVG and PNG
+- **Migration:** Database recreated on first run (backup first!)
+
+---
+
+## 🔄 Migration Guide
+
+### For Existing Installations
+
+#### Step 1: Backup Data
+```bash
+# Backup database
+cp db.sqlite db.sqlite.backup
+
+# Backup logos
+cp -r logos logos.backup
+```
+
+#### Step 2: Update Code
+```bash
+git pull origin main
+cd backend && go mod tidy
+cd ../frontend && npm install
+```
+
+#### Step 3: Migrate Files
+```bash
+# Create new structure
+mkdir -p logos/svg logos/png
+
+# Move existing files (manual process)
+# SVG files to logos/svg/
+# PNG files to logos/png/
+```
+
+#### Step 4: Update Database
+```bash
+# Database will auto-migrate on first run
+# Or manually run SQL migration
+```
+
+#### Step 5: Restart Services
+```bash
+docker-compose down
+docker-compose up --build
+```
+

+
+## 🧪 Testing New Features
+
+### 1. Test SVG Upload
+```bash
+# Visit admin panel
+http://localhost:3000/admin.html
+
+# Upload SVG file
+# Check: Both SVG and PNG should be created
+ls logos/svg/{uuid}.svg
+ls logos/png/{uuid}.png
+```
+
+### 2. Test Format Selection
+```bash
+# Get PNG
+curl http://localhost:8080/logos/{uuid}?format=png
+
+# Get SVG
+curl http://localhost:8080/logos/{uuid}?format=svg
+
+# Default (PNG)
+curl http://localhost:8080/logos/{uuid}
+```
+
+### 3. Test Logo List
+```bash
+curl http://localhost:8080/logos | jq
+```
+
+### 4. Test GitHub Actions
+```bash
+# Create PR with logo upload
+# Check that Actions run
+# Verify validation messages
+```
+
+---
+
+## 📈 Performance Impact
+
+### Improvements
+- ✅ **Faster Loading** - PNG serves faster than SVG
+- ✅ **Better Caching** - Optimized PNG files
+- ✅ **Dual Format** - Clients can choose best format
+- ✅ **Code Splitting** - Separate bundles for pages
+
+### Considerations

+# 🛠️ Utility Scripts
+
+Helpful PowerShell scripts for managing the Czech Clubs Logos API.
+
+## Available Scripts
+
+### setup-check.ps1
+Verifies your development environment is properly configured.
+
+**Usage:**
+```powershell
+.\scripts\setup-check.ps1
+```
+
+**Checks:**
+- Docker installation
+- Docker Compose installation
+- Go installation (optional)
+- Node.js installation (optional)
+- Project structure
+- Port availability
+
+### health-check.ps1
+Tests if the services are running and responding correctly.
+
+**Usage:**
+```powershell
+.\scripts\health-check.ps1
+```
+
+**Checks:**
+- Backend health endpoint
+- Frontend accessibility
+- API functionality
+
+**Note:** Services must be running first (`docker-compose up` or manual start)
+
+### test-api.ps1
+Comprehensive API endpoint testing suite.
+
+**Usage:**
+```powershell
+# Test against localhost
+.\scripts\test-api.ps1
+
+# Test against custom URL
+.\scripts\test-api.ps1 -BaseUrl "http://your-server:8080"
+```
+
+**Tests:**
+- Health check endpoint
+- Club search functionality
+- Club details retrieval
+- Logo metadata access
+- Error handling (invalid UUIDs)
+
+## Quick Reference
+
+```powershell
+# 1. Verify setup
+.\scripts\setup-check.ps1
+
+# 2. Start services
+docker-compose up -d
+
+# 3. Check health
+.\scripts\health-check.ps1
+
+# 4. Run API tests
+.\scripts\test-api.ps1
+```
+
+## Script Permissions
+
+If you get execution policy errors, run:
+```powershell
+Set-ExecutionPolicy -Scope CurrentUser -ExecutionPolicy RemoteSigned
+```
+
+## CI/CD Integration
+
+These scripts can be integrated into CI/CD pipelines:
+
+```yaml
+# GitHub Actions example
+- name: Verify Setup
+  run: pwsh ./scripts/setup-check.ps1
+
+- name: Health Check
+  run: pwsh ./scripts/health-check.ps1
+
+- name: Run API Tests
+  run: pwsh ./scripts/test-api.ps1
+```
+
+## Adding New Scripts
+
+When adding new scripts:
+1. Use `.ps1` extension
+2. Add parameter support
+3. Include help comments
+4. Use colored output
+5. Return proper exit codes
+6. Update this README
+
+## Tips
+
+- Run scripts from project root directory
+- Check script output colors:
+  - 🟢 Green = Success
+  - 🔴 Red = Error
+  - 🟡 Yellow = Warning
+  - ⚪ Gray = Info
+
+---

+🇨🇿 Czech Clubs Logos API
+
+A fullstack project for serving high-quality, transparent background logos of Czech football & futsal clubs.
+Logos are mapped by FAČR UUIDs (from facr.tdvorak.dev
+) to ensure consistency across projects.
+
+✨ Features
+
+⚽ Fetch Czech clubs metadata from FAČR Scraper API.
+
+🖼️ Upload & store full-quality transparent logos (SVG/PNG).
+
+🔄 Reuse FAČR UUID as a unique identifier.
+
+🌐 Serve logos through a simple CDN-style API.
+
+📝 Optional metadata (club name, city, colors, competition).
+
+📦 Self-hosted with Go backend + CDN storage.
+
+🔧 Tech Stack
+
+Backend: Golang (Gin or Fiber)
+
+Storage:
+
+Local /logos/{id}.svg
+
+Or cloud (Supabase / Cloudflare R2 / S3)
+
+Database: SQLite/Postgres (to link UUID ↔ metadata ↔ logo file)
+
+External API: facr.tdvorak.dev

+
+🚀 API Endpoints
+Search clubs
+
+Proxy FAČR search to help find correct UUID:
+
+GET /clubs/search?q=sparta
+→ proxies facr.tdvorak.dev/club/search?q=sparta
+
+Get club info
+GET /clubs/:id
+→ proxies facr.tdvorak.dev/club/{id}
+
+Upload logo
+
+Upload a full-quality SVG/PNG logo mapped to a FAČR UUID:
+
+POST /logos/:id
+FormData: file=@slavia.svg
+→ Saves to ./logos/{id}.svg
+→ Stores metadata in DB
+
+Get logo
+
+Serve logo by FAČR UUID:
+
+GET /logos/:id
+→ returns {id}.svg/png
+
+Get logo with metadata
+GET /logos/:id/json
+{
+  "id": "00000000-0000-0000-0000-000000000000",
+  "club": "AC Sparta Praha",
+  "type": "football",
+  "logo_url": "https://cdn.example.com/logos/00000000-0000-0000-0000-000000000000.svg"
+}
+
+📊 Example Workflow
+
+Search for a club:
+
+GET /clubs/search?q=Slavia
+→ returns UUID: 11111111-2222-3333-4444-555555555555
+
+
+Upload logo for club:
+
+POST /logos/11111111-2222-3333-4444-555555555555
+file=@slavia.svg
+
+
+Get logo:
+
+GET /logos/11111111-2222-3333-4444-555555555555
+→ returns full quality transparent SVG
+
+🔮 Future Ideas
+
+✍️ Web admin panel for uploading logos.
+
+🎨 Auto background remover (e.g., remove.bg API).
+
+🔎 Logo search by club name (maps internally to UUID).
+
+📦 Publish as NPM package (@czech-football/logos) or Go module.
+
+👉 This way, you’ll have a FAČR-aware logo CDN that anyone can integrate into websites, apps, or your SportCreative projects.
