 ## Release process
+
 ### Tagging of changes
 In order to have release notes automatically generated, changes need to be tagged with labels.
 The following labels are used (should be safe-explanatory):
 `breaking-change`, `bug`, `enhancement`.
 
 ### Release a new version
-Note: Releases need to be done from the `main` branch.
-
-1. Bump the version locally to (e.g. to `X.Y.Z`) and merge the change to `main`.
-2. Create a new draft release on GitHub using the
-[Create Draft Release](https://github.com/MannLabs/alphadia/actions/workflows/create_release.yml) workflow.
-You need to specify the commit to release, and the release tag (e.g. `vX.Y.Z`).
-3. Test the release manually.
-4. Add release notes and publish the release on GitHub.
-5. Run the [Publish on PyPi](https://github.com/MannLabs/alphadia/actions/workflows/publish_on_pypi.yml) workflow,
-specifying the release tag (e.g. `vX.Y.Z`).
-6. Run the [Publish Docker Image](https://github.com/MannLabs/alphadia/actions/workflows/publish_docker_image.yml) workflow,
-specifying the release tag (e.g. `vX.Y.Z`).
+This package uses a shared release process defined in the
+[alphashared](https://github.com/MannLabs/alphashared) repository. Please see the instructions
