 # Releasing
 
-## Process
-
 For version v0.x.y:
 
+## Prerequisites
+
+1. Update the `VERSION`, `VERSION_ID`, and `PRETTY_NAME` values in the `hook.yaml` file under `files -> "- path: etc/os-release"` to use `0.x.y`
+
+   ```bash
+   make update-os-release NEW_VERSION=0.x.y
+   ```
+
+1. Commit, push, PR, and merge the version changes
+
+   ```bash
+   git commit -sm "Update version to v0.x.y" hook.yaml
+   ```
+
+## Release Process
+
 1. Create the annotated tag
+
    > NOTE: To use your GPG signature when pushing the tag, use `SIGN_TAG=1 ./contrib/tag-release.sh v0.x.y` instead
-   - `./contrib/tag-release.sh v0.x.y`
+
+   ```bash
+   ./contrib/tag-release.sh v0.x.y
+   ```
+
 1. Push the tag to the GitHub repository. This will automatically trigger a [Github Action](https://github.com/tinkerbell/hook/actions) to create a release.
+
    > NOTE: `origin` should be the name of the remote pointing to `github.com/tinkerbell/boots`
-   - `git push origin v0.x.y`
+
+   ```bash
+   git push origin v0.x.y
+   ```
+
 1. Review the release on GitHub.
