-# Utapi Release Plan
-
-## Docker Image Generation
-
-Docker images are hosted on [ghcr.io](https://github.com/orgs/scality/packages).
-Utapi has one namespace there:
-
-* Namespace: ghcr.io/scality/utapi
-
-With every CI build, the CI will push images, tagging the
-content with the developer branch's short SHA-1 commit hash.
-This allows those images to be used by developers, CI builds,
-build chain and so on.
-
-Tagged versions of utapi will be stored in the production namespace.
-
-## How to Pull Docker Images
-
-```sh
-docker pull ghcr.io/scality/utapi:<commit hash>
-docker pull ghcr.io/scality/utapi:<tag>
-```
-
-## Release Process
-
-To release a production image:
-
-* Name the tag for the repository and Docker image.
-
-* Use the `yarn version` command with the same tag to update `package.json`.
-
-* Create a PR and merge the `package.json` change.
-
-* Tag the repository using the same tag.
-
-* [Force a build] using:
-  * A given branch that ideally matches the tag.
-  * The `release` stage.
-  * An extra property with the name `tag` and its value being the actual tag.
-
-[Force a build]:
