+## Changelog
+
+The changelog is automatically generated, so please do not edit it manually.
+
+For information, it is generated using a **Ruby** gem called [GitHub Changelog
+Generator](https://github.com/github-changelog-generator/github-changelog-generator).
+There is a POE task that will run this and update the changelog file.
+
+```console
+$ poe changelog
+```
+
+you also need to add a GitHub Personal Access Token to the config file. See the
+section in the
+[Documentation](http://127.0.0.1:8000/configuration/#add-a-github-personal-access-token)
+for information.
+
+**However, you should NOT include a change to the `CHANGELOG.md` file in your
+Pull Requests. This will be handled by the maintainers when a new release is
+made.**

 - add a default dockerfile? Maybe a docker-compose file as well?
 - take a look at the release-drafter GitHub action and see if worth using.
 - add the `actions/stale` action to the generated project.
-- add CLI command to generate the CHANGELOG.md file from the git history, using
-  `github_changelog_generator`. This would take the GitHub Key from the config
-  file if wanted. Note that without the Key, the GitHub API is rate limited to
-  50 requests per hour which is not usually usable unless you have a very small
-  project with few commits.
 - update the POE tasks to add help text to each task.
 - automatically create the new GitHub repository from the CLI. This would
   require the GitHub API key to be in the config file.
