-# Instructions for creating a new release
-
-Jupyter-Book is [hosted on the pypi repository](https://pypi.org/project/jupyter-book/).
-A new release is automatically created via GitHub Actions when a new release is added to the GitHub repository.
-
-To create a new release of Jupyter Book, follow the [release instructions in the `executablebooks/` meta repository](https://github.com/executablebooks/.github/blob/master/CONTRIBUTING.md#the-process-of-creating-a-release)
-
-## To create a release
-
-To create a new release, follow these steps:
-
-- Ensure that there aren't any extra issues to tackle in
-   [the milestone for the next release](https://github.com/executablebooks/jupyter-book/milestones?direction=asc&sort=due_date)
-- Bump `__init__.py` to the version for the release. Use
-  [semantic versioning](https://semver.org/) to decide what version to choose.
-  For example:
-
-  ```
-  __version__ = "0.6.1"
-  ```
-- Create a "release commit":
-
-  ```
-  git add jupyter_book
-  git commit -m "🚀RELEASE: <version-number>"
-  git push upstream master
-  ```
-- [Create a new release](https://github.com/executablebooks/jupyter-book/releases/new) on GitHub.
-  The tag and title should be `v<version-number>`. For example, `v0.6.1`.
-  - GitHub Actions will automatically deploy this release to PyPI using
-    [this configuration](https://github.com/executablebooks/jupyter-book/blob/master/.github/workflows/tests.yml#L86).
-  - Confirm that a new version of the package [is posted to pypi](https://pypi.org/project/jupyter-book/)
-- Add a changelog for the latest version by using `github-activity`:
-
-  ```
-  github-activity executablebooks/jupyter-book -s <old-version-tag> -u <new-version-tag>
-  ```
-
-  Paste the result into the release description on GitHub.
-- You're done! 🎉
