-# GameServers.World - Billing Module
-
-## Overview
-The billing module is a complete standalone website for selling game servers. It can be deployed on the same machine as the GSP panel or on a completely separate external web host.
-
-## Documentation System
-
-### Visual TODO System ✅
-As of December 19, 2024, all game documentation includes completion tracking:
-
-- **Complete Documentation:** Displays with normal name (e.g., "Minecraft Server")
-- **Incomplete Documentation:** Displays with "TODO: " prefix (e.g., "TODO: Arma 3")
-
-### Current Status
-- **Complete:** 1 game (Minecraft - comprehensive template)
-- **Incomplete:** 146 games (marked with TODO prefix)
-
-### Documentation Template Standard
-All complete documentation should match the Minecraft template:
-- Comprehensive ports table (ALL ports with purposes)
-- Firewall configurations (UFW, FirewallD, Windows, iptables)
-- Startup parameters with detailed explanations
-- Troubleshooting sections with specific solutions
-- Performance optimization tips
-- Security best practices
-- Resource links with citations
-
-### Viewing Documentation
-- Browse to `docs.php` to see all game documentation
-- Games with "TODO: " prefix need comprehensive research and writing
-- Click any game to view its documentation page
-
-### Marking Documentation Complete
-When game documentation is finished:
-1. Edit `docs/{game}/metadata.json`
-2. Change `"complete": false` to `"complete": true`
-3. The TODO prefix will automatically disappear
-

-## Development Guidelines
-
-### Adding New Game Documentation
-1. Create folder: `docs/{game-slug}/`
-2. Create `metadata.json`:
-   ```json
-   {
-     "name": "Game Name",
-     "description": "Brief description",
-     "category": "game",
-     "order": 100,
-     "complete": false
-   }
-   ```
-3. Create `index.php` following Minecraft template
-4. Add optional `icon.png` or `icon.jpg`
-5. When complete, set `"complete": true` in metadata
-
-### Research Sources for Game Documentation

-- Steam Community Guides (highly-rated)
-- Reddit communities (r/gameservers, game-specific)

-- Official game forums
-- User-contributed solutions and fixes
-
-### Documentation Quality Standards

-## Next Priorities
-
-### Phase 2: ARMA Family + DayZ (HIGH PRIORITY)
-1. Arma 3
-2. Arma 2: Operation Arrowhead
-3. Arma 2: Combined Operations
-4. DayZ Standalone
-5. DayZ Mod
-
-### Phase 3: Popular Multiplayer Games
-- Counter-Strike family (1.6, Source, CS2, CS:GO)
-- Survival/Building (Rust, Terraria, Valheim, ARK)
-- Co-op Shooters (L4D series, Killing Floor series, TF2)
-- Tactical Shooters (Insurgency series, Squad)
-
-### Phase 4: Remaining Games
-- All other 50+ game folders in alphabetical order
-
-## Testing Checklist
-
-### PayPal Integration
-- [ ] User can add servers to cart
-- [ ] PayPal checkout button works
-- [ ] Payment completes successfully
-- [ ] Success page displays correctly
-- [ ] No `NO_USER_SESSION` errors in logs
-
-### Documentation System
-- [ ] docs.php displays all games correctly
-- [ ] TODO prefix shows for incomplete docs
-- [ ] Complete docs show without TODO prefix
-- [ ] Individual game pages load correctly
-- [ ] Navigation links work within documentation
-
-### Cart Functionality

-
-## Technical Notes
-
-### Session Management
-- **CRITICAL:** Always use `session_name("opengamepanel_web")` before `session_start()`
-- Sessions are separate from panel sessions
-- User authentication stored in `$_SESSION['website_user_id']`
-
-### Database Connection
-- Uses mysqli with credentials from `includes/config.inc.php`
-- All database operations use native mysqli functions
-- Never use panel-specific functions
-
-### Standalone Design
-- Module must work on external hosting
-- No dependencies on panel files
-- All paths use `__DIR__` relative references
-- MySQL connection direct (not through panel)
-
-## Support & Resources
-- Main project: GameServerPanel/GSP
-- Branch: Panel-unstable
-- Documentation: Browse `docs.php` for game-specific guides
-- Issues: Check logs in `modules/billing/logs/`
