-## Backend (FastAPI)
+## Quick start (Docker - primary)
+
+Docker is the recommended way to run Magent. It includes the backend and frontend with sane defaults.
+
+```bash
+docker compose up --build
+```
+
+Then open:
+
+- Frontend: http://localhost:3000
+- Backend: http://localhost:8000
+
+### Docker setup steps
+
+1) Create `.env` with your service URLs and API keys.
+2) Run `docker compose up --build`.
+3) Log in at http://localhost:3000.
+4) Visit Settings to confirm service health.
+
+### Docker environment variables (sample)

+## Troubleshooting
+
+### Login fails
+
+- Make sure `ADMIN_USERNAME` and `ADMIN_PASSWORD` are set in `.env`.
+- Confirm the backend is reachable: `http://localhost:8000/health` (or see container logs).
+
+### Services show as down
+
+- Check the URLs and API keys in Settings.
+- Verify containers can reach each service (network/DNS).
+
+### No recent requests
+
+- Confirm Jellyseerr credentials in Settings.
+- Run a full sync from Settings -> Requests.
+
+### Docker images not updating
+
+- Run `docker compose up --build` again.
+- If needed, run `docker compose down` first, then rebuild.
