 ### Docker Deployment
 
-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.
+The provided `docker-compose.yml` is standalone: copy that file to an empty deployment directory and run Compose there. You do not need to clone the repository or keep any Dockerfile for a normal deployment. Application data is stored in the `./data` directory next to the Compose file.
 
 #### Standard deployment
 
 Start nodecast-tv without the optional Laya runtime:
 
 ```bash
-docker compose up -d --build nodecast-tv
+docker compose up -d
 ```
 
-The application will be available at `http://localhost:3000`. Live channel analysis continues to work in **Standard** mode when Laya is not running.

-The Laya model cache is persisted under `./data/models/laya`. The first analysis can take longer while the runtime downloads or loads its model.
+The optional service uses `${LAYA_IMAGE}` when set, or the project image `gitea.anthonybouteiller.ovh/blomios/nodecast-tv-laya:latest` by default. That image must be published and accessible in your environment. If it is hosted under another registry or tag, create a `.env` file next to `docker-compose.yml`:

+```env
+NODECAST_IMAGE=gitea.anthonybouteiller.ovh/blomios/nodecast-tv:latest
+LAYA_IMAGE=registry.example.com/team/nodecast-tv-laya:latest
+```
+
+No third-party Laya image is selected implicitly. If no suitable Laya image is available, omit the `laya` profile and continue using Standard mode. The Laya model cache is persisted under `./data/models/laya`; its first analysis can take longer while the runtime downloads or loads the model.

-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.
+Repository maintainers can still build and publish the nodecast-tv image with `./scripts/docker-build-push.sh`; this script is not needed by Compose users.
