 Once the prep work is completed, the actual release is straight forward:
 
+* First, ensure that you have installed your projects dependencies:
+
 ```
 yarn install
-yarn release
 ```
 
-The `release` script leverages
-[release-it](https://github.com/release-it/release-it/) to do the mechanical
-release process. It will prompt you through the process of choosing the version
-number, tagging, pushing the tag and commits, etc.
+* Second, ensure that you have obtained a
+  [GitHub personal access token][generate-token] with the `repo` scope (no
+  other permissions are needed). Make sure the token is available as the
+  `GITHUB_AUTH` environment variable.
+
+  For instance:
+
+  ```bash
+  export GITHUB_AUTH=abc123def456
+  ```
+
+[generate-token]: https://github.com/settings/tokens/new?scopes=repo&description=GITHUB_AUTH+env+variable
+
+* And last (but not least 😁) do your release.
+
+```
+npx release-it
+```
+
+[release-it](https://github.com/release-it/release-it/) manages the actual
+release process. It will prompt you to to choose the version number after which
+you will have the chance to hand tweak the changelog to be used (for the
+`CHANGELOG.md` and GitHub release), then `release-it` continues on to tagging,
+pushing the tag and commits, etc.
