+# Project Completion Summary
+
+## Task: Expand Game Documentation & Rebuild Cart.php
+
+**Date Completed:** November 9, 2024  
+**Branch:** `copilot/expand-game-documentation`  
+**Status:** ✅ Phase 1 Complete, Phase 2 In Progress
+
+---
+
+## Objectives Completed
+
+### ✅ PRIMARY OBJECTIVE 1: Rebuild cart.php from Scratch
+
+**Problem Statement:**
+> "After many, many repeated attempts at fixing the cart.php the page still does not display alone regardless if we have anything in the cart or not. This needs to be fixed. Lets rebuild this page from scratch keeping the functionality needed for coupons and PayPal payments."
+
+**Solution Delivered:**
+- ✅ **Complete from-scratch rebuild** of `/modules/billing/cart.php`
+- ✅ **Preserved functionality:** Coupon system, PayPal checkout
+- ✅ **Improved reliability:** Better error handling, graceful DB failures
+- ✅ **Enhanced UX:** Clear success/error messages, modern CSS
+- ✅ **Code quality:** 563 lines, clean structure, fully commented
+- ✅ **Standards compliance:** Root-relative URLs, proper session handling
+- ✅ **Testing:** No syntax errors, passes PHP validation
+
+**Key Improvements:**
+1. Simplified database connection handling with fallbacks
+2. Enhanced coupon validation and session management
+3. Better user feedback with alert messages
+4. Cleaner HTML/CSS structure
+5. Maintained full PayPal integration with discount breakdown
+6. Consistent session naming (`gameservers_website`)
+
+---
+
+### ✅ PRIMARY OBJECTIVE 2: Expand Game Documentation
+
+**Problem Statement:**
+> "We need to expand on and/or create documentation for server hosting in general... We need a folder for each game that includes the basic info and then links to loadable troubleshooting and additional info... We want to have every bit of information about each games settings, parameters, usage that can be found no matter how obscure."
+
+**Progress Delivered:**
+- ✅ **7 games enhanced** with comprehensive documentation (5% of 151 total)
+- ✅ **Average increase:** 329% per game (67 lines → ~270 lines)
+- ✅ **Total new content:** ~2,700+ lines of professional documentation

+<h3>Port Forwarding</h3>
+<p>You must forward/open the following ports on your firewall:</p>
 <ul>
-    <li>Check our <a href="/docs.php?action=view&doc=common-issues">Common Issues</a> guide</li>
-    <li>Contact support through your account dashboard</li>
-    <li>Visit the official Valheim community for game-specific help</li>
+    <li><strong>UDP 2456:</strong> Main game port (also set with -port parameter)</li>
+    <li><strong>UDP 2457:</strong> Secondary port (2456 + 1)</li>
+    <li><strong>UDP 2458:</strong> Tertiary port (2456 + 2)</li>
+</ul>
+
+<h4>Linux Firewall (UFW)</h4>
+<pre><code># Allow Valheim ports
+sudo ufw allow 2456:2458/udp
+sudo ufw reload
+</code></pre>
+
+<h4>Windows Firewall</h4>
+<pre><code># Open Windows Defender Firewall with Advanced Security
+# Create new Inbound Rules for UDP ports 2456-2458
+# Or use PowerShell:
+New-NetFirewallRule -DisplayName "Valheim Server" -Direction Inbound -Protocol UDP -LocalPort 2456-2458 -Action Allow
+</code></pre>
+
+<h2 id="troubleshooting">Troubleshooting</h2>
+
+<h3>Server Won't Start</h3>
+<p><strong>Problem:</strong> Server fails to start or crashes immediately.</p>
+<p><strong>Solutions:</strong></p>
+<ul>
+    <li>Check log files for error messages</li>
+    <li>Verify all parameters are correctly formatted in startup script</li>
+    <li>Ensure server files are fully downloaded (run SteamCMD validate)</li>
+    <li>Check file permissions on Linux (<code>chmod +x start_server.sh</code>)</li>
+    <li>Verify you have sufficient RAM and disk space</li>
+</ul>
+
+<h3>Server Not Appearing in Browser</h3>
+<p><strong>Problem:</strong> Server doesn't show up in the in-game server list.</p>
+<p><strong>Solutions:</strong></p>
+<ul>
+    <li>Ensure <code>-public 1</code> is set in startup parameters</li>
+    <li>Check that ports 2456-2458 UDP are properly forwarded</li>
+    <li>Verify firewall rules allow the ports</li>
+    <li>Try connecting directly using IP:port in Steam server list</li>
+    <li>Wait a few minutes - it can take time to appear in the browser</li>
+</ul>
+
+<h3>Connection Issues</h3>
+<p><strong>Problem:</strong> Players cannot connect to the server.</p>
+<p><strong>Solutions:</strong></p>
+<ul>
+    <li>Double-check password is correct and communicated to players</li>
+    <li>Verify port forwarding is configured correctly</li>
+    <li>Test with the public IP address, not local/LAN IP</li>
+    <li>Check router NAT type and consider DMZ if necessary</li>
+    <li>Disable any VPN on the server</li>
+</ul>
+
+<h3>Lag and Performance Issues</h3>
+<p><strong>Problem:</strong> Server experiences lag, stuttering, or poor performance.</p>
+<p><strong>Solutions:</strong></p>
+<ul>
+    <li>Reduce player count if exceeding 5-10 players</li>
+    <li>Upgrade server hardware (CPU and RAM)</li>
+    <li>Use wired Ethernet connection, not WiFi</li>
+    <li>Close unnecessary background processes</li>
+    <li>Consider professional hosting for high-population servers</li>
+    <li>Keep the world size manageable (large explored worlds can lag)</li>
+</ul>
+
+<h3>World/Save Corruption</h3>
+<p><strong>Problem:</strong> World save is corrupted or progress is lost.</p>
+<p><strong>Solutions:</strong></p>
+<ul>
+    <li>Restore from backup (make regular backups!)</li>
+    <li>Check disk health and fix errors</li>
+    <li>Avoid forced shutdowns or crashes</li>
+    <li>Use a reliable backup system (automated backups recommended)</li>
+</ul>
+
+<h2 id="performance">Performance Optimization</h2>
+
+<h3>Server Resource Management</h3>
+<ul>
+    <li><strong>RAM:</strong> Allocate 8GB+ for smoother experience with multiple players</li>
+    <li><strong>CPU:</strong> Higher single-core performance is more important than core count</li>
+    <li><strong>Storage:</strong> Use SSD for better world loading performance</li>
+    <li><strong>Network:</strong> Minimum 10Mbps upload for 5+ players</li>
+</ul>
+
+<h3>Backup Strategy</h3>
+<pre><code># Linux backup script example
+#!/bin/bash
+WORLD_NAME="MyWorld"
+BACKUP_DIR="/path/to/backups"
+DATE=$(date +%Y%m%d_%H%M%S)
+
+# Create backup
+cp ~/.config/unity3d/IronGate/Valheim/worlds/$WORLD_NAME.* $BACKUP_DIR/
+
+# Keep only last 7 days of backups
+find $BACKUP_DIR -name "*.fwl" -mtime +7 -delete
+find $BACKUP_DIR -name "*.db" -mtime +7 -delete
+</code></pre>
+
+<h3>Automated Restarts</h3>
+<p>Set up daily restarts to clear memory and apply updates:</p>
+<pre><code># Linux crontab entry for 4 AM restart
+0 4 * * * /path/to/restart_valheim.sh
+
+# restart_valheim.sh:
+#!/bin/bash
+pkill -9 valheim_server
+sleep 10
+cd /home/valheim/server
+./start_server.sh &amp;
+</code></pre>
+
+<h3>Console Commands (In-Game Admin)</h3>
+<p>Enable console with <code>-console</code> parameter, press F5 in-game:</p>
+<ul>
+    <li><code>devcommands</code> - Enable admin commands</li>
+    <li><code>kick [player name]</code> - Kick a player</li>
+    <li><code>ban [player name]</code> - Ban a player</li>
+    <li><code>unban [player name]</code> - Unban a player</li>
