+
+### Prerequisite
+* [ ] Make sure your problem is not listed in [the common build problems](https://github.com/pyenv/pyenv/wiki/Common-build-problems).
+* [ ] Make sure no duplicated issue has already been reported in [the pyenv-virtualenv issues](https://github.com/pyenv/pyenv-virtualenv/issues). You should look in closed issues, too.
+* [ ] Make sure you are not asking us to help solving your specific issue.
+  * GitHub issues is opened mainly for development purposes. If you want to ask someone to help solving your problem, go to some community site like [Gitter](https://gitter.im/yyuu/pyenv), [StackOverflow](https://stackoverflow.com/questions/tagged/pyenv), etc.
+* [ ] Make sure your problem is not derived from packaging (e.g. [Homebrew](https://brew.sh)).
+  * Please refer to the package documentation for the installation issues, etc.
+* [ ] Make sure your problem is not derived from other plugins.
+  * This repository is maintaining the `pyenv-virtualenv` plugin only. Please refrain from reporting issues of other plugins here.

+Creating a release
+==================
+
+The release of the new version of Pyenv is done via GitHub Releases.
+
+Release checklist:
+* Start [drafting a new release on GitHub](https://github.com/pyenv/pyenv-virtualenv/releases) to generate a summary of changes. Save the summary locally.
+  * The summary may need editing. E.g. rephrase entries, delete/merge entries that are too minor or irrelevant to the users (e.g. typo fixes, CI)
+* Push the version number in `bin/pyenv-virtualenv`
+  * Minor version is pushed if there are significant functional changes (not e.g. bugfixes/formula adaptations/supporting niche use cases).
+  * Major version is pushed if there are breaking changes
+* Update `CHANGELOG.md` with the new version number and the edited summary (only the changes section), reformatting it like the rest of the changelog sections
+* Commit the changes locally into `master`
+* Create a new tag with the new version number and push the changes including the tag
+* Create a new release on GitHub based on the tag, using the saved summary
