 ### Docker Deployment
 
-You can run nodecast-tv easily using Docker.
+The repository includes a ready-to-use `docker-compose.yml`. Run these commands from the repository directory so Compose uses that file and the local Dockerfiles.
 
-1.  Create a `docker-compose.yml` file (or copy the one from this repo):
+#### Standard deployment
 
-    ```yaml
-    services:
-      nodecast-tv:
-        image: gitea.anthonybouteiller.ovh/blomios/nodecast-tv:latest
-        container_name: nodecast-tv
-        ports:
-          - "3000:3000" # Host:Container
-        volumes:
-          - ./data:/app/data
-        restart: unless-stopped
-        environment:
-          - NODE_ENV=production
-          - PORT=3000 # Optional: Internal container port
-    ```
+Start nodecast-tv without the optional Laya runtime:
 
-2.  Run the container:
 ```bash
-    docker-compose up -d
+docker compose up -d --build nodecast-tv
 ```
 
-The application will be available at `http://localhost:3000`.
+The application will be available at `http://localhost:3000`. Live channel analysis continues to work in **Standard** mode when Laya is not running.
+
+#### Optional Laya runtime
+
+Laya provides optional local-AI assistance for channel grouping and language detection. It is behind the Compose profile named `laya`, so a plain `docker compose up -d` does not start it.
+
+Start nodecast-tv and Laya together:
+
+```bash
+docker compose --profile laya up -d --build
+```
+
+Rebuild and recreate both services after an update:
+
+```bash
+docker compose --profile laya up -d --build --force-recreate
+```
+
+Rebuild and recreate only Laya:
+
+```bash
+docker compose --profile laya up -d --build --force-recreate laya
+```
+
+The Laya model cache is persisted under `./data/models/laya`. The first analysis can take longer while the runtime downloads or loads its model.
+
+Inside Compose, nodecast-tv reaches Laya at `http://laya:8000`. When running nodecast-tv directly on the host with a separately exposed Laya runtime, use:
+
+```bash
+LAYA_BASE_URL=http://localhost:8000 npm start
+```
+
+`http://laya:8000` is a Compose-internal hostname and does not resolve from a host process.
 
 To publish the image, log in if needed with `docker login gitea.anthonybouteiller.ovh`, then run `./scripts/docker-build-push.sh`. Use `--no-push` to build it locally without publishing.

 ## Troubleshooting
 
+### Docker Compose and optional Laya
+
+Check that you are in the repository directory and that Compose sees both services:
+
+```bash
+docker compose config --services
+docker compose --profile laya config --services
+docker compose config --profiles
+```
+
+The standard configuration should list `nodecast-tv`; with the `laya` profile enabled it should list both `nodecast-tv` and `laya`. The available profiles should include `laya`.
+
+If `docker compose ... laya` reports `no such service: laya`, you are usually using an old or different Compose file, or running the command from the wrong directory. Update the checkout, change to the directory containing this repository's `docker-compose.yml`, and run `docker compose config --services` again.
+
+If Settings reports **“The optional Laya runtime is unavailable”**, nodecast-tv remains usable and falls back to Standard analysis. To diagnose Laya, run:
+
+```bash
+docker compose --profile laya ps
+docker compose --profile laya logs nodecast-tv
+docker compose --profile laya logs laya
+docker compose --profile laya config
+```
+
+After configuration or image changes, perform a clean recreation:
+
+```bash
+docker compose --profile laya up -d --build --force-recreate
+```
+
+To recreate only the optional runtime:
+
+```bash
+docker compose --profile laya up -d --build --force-recreate laya
+```
