+# Release docs
+
+This doc contains information for releasing a new version.
+
+## Create a release
+
+Creating a release can be done by pushing a tag to the GitHub repository (beginning with `v`).
+
+The [release workflow](../../.github/workflows/release.yaml) will take care of creating the GitHub release and will publish artifacts.
+
+```shell
+VERSION="v0.0.1"
+TAG=$VERSION
+
+git tag $TAG -m "tag $TAG" -a
+git push origin $TAG
+```
+
+## Publish documentation
+
+Publishing the documentation for a release is decoupled from cutting a release.
+
+To publish the documentation push a tag to the GitHub repository (beginning with `docs-v`).
+
+```shell
+VERSION="v0.0.1"
+TAG=docs-$VERSION
+
+git tag $TAG -m "tag $TAG" -a
+git push origin $TAG
+```
