## 🔧 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
```

## ⚠️ 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!)

cd ../frontend && npm install
```

#### Step 3: Migrate Files

## 🧪 Testing New Features

### 1. Test SVG Upload
```bash
# Visit admin panel

# 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)

```

### 3. Test Logo List

# Create PR with logo upload
# Check that Actions run
# Verify validation messages
```
