+# DocFast CI/CD Pipeline Setup - COMPLETED ✅
+
+## What Was Implemented
+
+### ✅ Forgejo Actions Workflow
+- **File**: `.forgejo/workflows/deploy.yml`
+- **Trigger**: Push to `main` branch
+- **Process**: 
+  1. SSH to production server (167.235.156.214)
+  2. Pull latest code from git
+  3. Tag current Docker image for rollback (`rollback-YYYYMMDD-HHMMSS`)
+  4. Build new Docker image with `--no-cache`
+  5. Stop current services (30s graceful timeout)
+  6. Start new services with `docker compose up -d`
+  7. Health check at `http://127.0.0.1:3100/health` (30 attempts, 5s intervals)
+  8. **Auto-rollback** if health check fails
+  9. Cleanup old rollback images (keeps last 5)
+
+### ✅ Rollback Mechanism
+- **Automatic**: Built into the deployment workflow
+- **Manual Script**: `scripts/rollback.sh` for emergency use
+- **Image Tagging**: Previous images tagged with timestamps
+- **Auto-cleanup**: Removes old rollback images automatically
+
+### ✅ Documentation
+- **`DEPLOYMENT.md`**: Complete deployment guide
+- **`CI-CD-SETUP-COMPLETE.md`**: This summary
+- **Inline comments**: Detailed workflow documentation
+
+### ✅ Git Integration
+- Repository: `git@git.cloonar.com:openclawd/docfast.git` 
+- SSH access configured with key: `/home/openclaw/.ssh/docfast`
+- All CI/CD files committed and pushed successfully
+
+## What Needs Manual Setup (5 minutes)
+
+### 🔧 Repository Secrets
+Go to: https://git.cloonar.com/openclawd/docfast/settings/actions/secrets
+
+Add these 3 secrets:
+1. **SERVER_HOST**: `167.235.156.214`
+2. **SERVER_USER**: `root`  
+3. **SSH_PRIVATE_KEY**: (copy content from `/home/openclaw/.ssh/docfast`)
+
+### 🧪 Test the Pipeline
+1. Once secrets are added, push any change to main branch
+2. Check Actions tab: https://git.cloonar.com/openclawd/docfast/actions
+3. Watch deployment progress
+4. Verify with: `curl http://127.0.0.1:3100/health`
+
+## How to Trigger Deployments
+
+- **Automatic**: Any push to `main` branch
+- **Manual**: Push a trivial change (already prepared: VERSION file)
+
+## How to Rollback
+
+### Automatic Rollback
+- Happens automatically if new deployment fails health checks
+- No manual intervention required
+
+### Manual Rollback Options
+```bash
+# Option 1: Use the rollback script
+ssh root@167.235.156.214
+cd /root/docfast  
+./scripts/rollback.sh
+
+# Option 2: Manual Docker commands
+ssh root@167.235.156.214
+docker compose down
+docker images | grep rollback  # Find latest rollback image
+docker tag docfast-docfast:rollback-YYYYMMDD-HHMMSS docfast-docfast:latest
+docker compose up -d
+```
+
+## Monitoring Commands
+
+```bash
+# Health check
+curl http://127.0.0.1:3100/health
+
+# Service status  
+docker compose ps
+
+# View logs
+docker compose logs -f docfast
+
+# Check rollback images available
+docker images | grep docfast-docfast
+```
+
+## Files Added/Modified
+
+```
+.forgejo/workflows/deploy.yml    # Main deployment workflow
+scripts/rollback.sh             # Emergency rollback script
+scripts/setup-secrets.sh        # Helper script (API had auth issues)
+DEPLOYMENT.md                   # Deployment documentation  
+CI-CD-SETUP-COMPLETE.md        # This summary
+VERSION                         # Test file for pipeline testing
+```
+
+## Next Steps
+
+1. **Set up secrets** in Forgejo (5 minutes)
+2. **Test deployment** by making a small change
+3. **Verify** the health check endpoint works
+4. **Document** any environment-specific adjustments needed
+
+## Success Criteria ✅
+
+- [x] Forgejo Actions available and configured
+- [x] Deployment workflow created and tested (syntax)
+- [x] Rollback mechanism implemented (automatic + manual)
+- [x] Health check integration (`/health` endpoint)  
+- [x] Git repository integration working
+- [x] Documentation complete
+- [x] Test change ready for pipeline verification
+
+**Ready for production use once secrets are configured!** 🚀
