+# Arbiter 3.0 Deployment Guide
+
+**Location:** Command Center (63.143.34.217)  
+**Service:** `arbiter-3` (systemd)  
+**Directory:** `/opt/arbiter-3.0`  
+**Dashboard:** https://discord-bot.firefrostgaming.com/admin
+
+---
+
+## ⚠️ IMPORTANT: Arbiter is NOT a Git Repo
+
+`/opt/arbiter-3.0` on Command Center is **not** a git repository. It's a deployment target.
+
+**Source of truth:** `firefrost-services` repo → `services/arbiter-3.0/`
+
+**Why?** Production servers shouldn't have git credentials or .git history. Deploy by copying files.
+
+---
+
+## Quick Deploy (One Command)
+
+**On Command Center:**
+```bash
+curl -fsSL https://git.firefrostgaming.com/firefrost-gaming/firefrost-services/raw/branch/main/services/arbiter-3.0/deploy.sh | bash
+```
+
+**Or if deploy.sh is already on server:**
+```bash
+bash /opt/arbiter-3.0/deploy.sh
+```
+
+---
+
+## Manual Deploy
+
+```bash
+# On Command Center
+cd /tmp
+rm -rf firefrost-services
+git clone https://git.firefrostgaming.com/firefrost-gaming/firefrost-services.git
+cp -r firefrost-services/services/arbiter-3.0/src/* /opt/arbiter-3.0/src/
+systemctl restart arbiter-3
+rm -rf firefrost-services
+```
+
+---
+
+## Verify Deployment
+
+```bash
+# Check service status
+systemctl status arbiter-3
+
+# Check logs
+journalctl -u arbiter-3 -n 50
+
+# Test dashboard
+curl -s https://discord-bot.firefrostgaming.com/admin | head -5
+```
+
+---
+
+## Common Issues
+
+### "fatal: not a git repository"
+**Cause:** Someone tried to `git pull` in `/opt/arbiter-3.0`  
+**Fix:** Use the deploy script or manual copy method above
+
+### "/tmp/firefrost-services already exists"
+**Cause:** Previous deploy didn't clean up  
+**Fix:** `rm -rf /tmp/firefrost-services` then try again
+
+### Service fails to start
+**Check:** `journalctl -u arbiter-3 -n 50`  
+**Common causes:**
+- Missing .env file
+- Database connection failed
+- Port already in use
+- Syntax error in code
+
+---
+
