+# CI/CD Setup Instructions
+
+## ✅ What's Done
+
+1. **Gitea Actions workflow** created (`.gitea/workflows/ci-cd.yaml`)
+   - Build job: Verify Astro build works
+   - Deploy job: Build Docker image + push to registry + trigger Portainer
+
+2. **Docker files** created:
+   - `Dockerfile` - Multi-stage build (Node + nginx)
+   - `docker-compose.yml` - Local testing
+   - `nginx.conf` - SPA routing + cache headers
+   - `.dockerignore` - Optimize build
+
+3. **Pushed to git** - CI will run on next push to main branch

+
+## 🔧 Manual Steps Required
+
+### 1. Configure Gitea Secrets
+
+Go to: https://gitlab.impresion3d.pro/root/davidaragon-portfolio/settings/secrets
+
+Add these secrets:
+
+#### `DOCKER_USERNAME`
+```
+root
+```
+
+#### `DOCKER_PASSWORD`
+```
+<your Gitea personal access token with registry permissions>
+```
+
+#### `PORTAINER_WEBHOOK_URL`
+```
+<webhook URL from Portainer stack - see step 2>
+```
+
+### 2. Create Portainer Stack
+
+1. Go to Portainer: http://192.168.1.30:9000
+2. Navigate to: **Stacks** → **Add stack**
+3. Name: `davidaragon-portfolio`
+4. Build method: **Git Repository** or **Web editor**
+
+#### Stack compose file:
+
+```yaml
+version: '3.8'
+
+services:
+  portfolio:
+    image: gitlab.impresion3d.pro/root/davidaragon-portfolio:latest
+    container_name: davidaragon-portfolio
+    ports:
+      - "8081:80"
+    restart: unless-stopped
+    environment:
+      - NODE_ENV=production
+    networks:
+      - web
+
+networks:
+  web:
+    external: true
+```
+
+5. Deploy the stack
+6. Go to stack **Webhooks** tab
+7. Create webhook for service `portfolio`
+8. Copy webhook URL (format: `http://192.168.1.30:9000/api/stacks/webhooks/...`)
+9. Add this URL as `PORTAINER_WEBHOOK_URL` secret in Gitea (step 1)
+
+### 3. Optional: Configure Gitea Runner
+
+If no runners registered yet:
+
+```bash
+# On server 192.168.1.30 (port 2222)
+docker run -d \
+  --name gitea-runner-portfolio \
+  --restart unless-stopped \
+  -e GITEA_INSTANCE_URL=https://gitlab.impresion3d.pro \
+  -e GITEA_RUNNER_REGISTRATION_TOKEN=<your_token> \
+  -e GITEA_RUNNER_NAME=ubuntu-latest \
+  -v /var/run/docker.sock:/var/run/docker.sock \
+  gitea/act_runner:latest
+```
+
+Get registration token from: https://gitlab.impresion3d.pro/admin/actions/runners
+
+---
+
+## 🚀 How It Works
+
+### On Every Push to Main:
+
+1. **Build job** runs:
+   - Install Node.js 20
+   - Install dependencies (`npm ci`)
+   - Build Astro site (`npm run build`)
+   - Upload `dist/` artifact
+
+2. **Deploy job** runs (only if build succeeds):
+   - Download `dist/` artifact
+   - Build Docker image (multi-stage)
+   - Push to Gitea registry: `gitlab.impresion3d.pro/root/davidaragon-portfolio:latest`
+   - Trigger Portainer webhook → Portainer pulls new image and restarts container
+
+### Result:
+- Site auto-deployed to http://192.168.1.30:8081
+- No manual intervention needed after initial setup
+
+---
+
+## 🧪 Test Locally
+
+```bash
+cd ~/code_ubuntu/davidaragon-portfolio
+
+# Build and run with Docker Compose
+docker-compose up --build
+
+# Visit: http://localhost:8080
+```
+
+---
+
+## 📝 Next Steps
+
+1. Configure secrets in Gitea (step 1)
+2. Create Portainer stack (step 2)
+3. Add webhook URL to Gitea secrets
+4. Push any commit to main → CI/CD runs automatically!
