+## Deployment
+
+The [docker.yml](./.github/workflows/docker.yml) workflow builds a Docker image and pushes it to a Scaleway container registry. The supply server is deployed via a Scaleway serverless container. CI will not automatically deploy the latest Docker image to the serverless container so you must do that manually if you want to deploy a new version of the supply server.
