+In the `score.yaml` file, the Developer can request a `llm-model` resource to use it in their app by injecting the corresponding `url` generated when this Score file will be deployed. By using `score-compose init --provisioners`, the actual implementation of the `llm-model` resource is downloaded locally (you can [look at its definition here](https://docs.score.dev/examples/resource-provisioners/community/llm-model/score-compose/template/dmr-llm-model-via-service-provider/), Docker Model Runner is used). Then, with `score-compose generate`, both the `my-container` and the `llm-model` services are generated into a `compose.yaml` file. Finally, `docker compose up` will deploy them.
