 ### 3. Run
 
+**Option A — Single Container** (recommended for simplicity):
+
+```bash
+docker compose -f docker-compose.single.yml up -d
+```
+
+One container runs everything (nginx + backend). Port `8080`.
+
+**Option B — Two Containers** (recommended for production):
+
 ```bash
 docker compose up -d
 ```
 
+Separate backend and frontend containers with internal networking.
+
+**Option C — Docker Run** (no compose needed):
+
+```bash
+docker run -d \
+  --name oci-cis-agent \
+  -p 8080:8080 \
+  -v agent-data:/data \
+  -e APP_SECRET=$(openssl rand -hex 64) \
+  -e TZ=America/Sao_Paulo \
+  <OCIR_REGION>.ocir.io/<OCIR_NAMESPACE>/oci-cis-agent:latest
+```
+
 ### 4. Access
