+# Release process
+
+When releasing a new version of Pest there are some checks and updates that need to be done:
+
+- Clear your local repository with: `git add . && git reset --hard && git checkout master` 
+- On the GitHub repository, check the contents of [github.com/pestphp/pest/compare/{latest_version}...master](https://github.com/pestphp/pest/compare/{latest_version}...master) and update the [changelog](CHANGELOG.md) file with the main changes for this release
+- Update the version number in [src/Pest.php](src/Pest.php)
+- Run the tests locally using: `composer test`
+- Commit the CHANGELOG and Pest file with the message: `git commit -m "docs: update changelog"`
+- Push the changes to GitHub
+- Check that the CI is passing as expected: [github.com/pestphp/pest/actions](https://github.com/pestphp/pest/actions)
+- Tag and push the tag with `git tag vX.X.X && git push --tags`
+
+### Plugins
+
+Plugins should be versioned using the same major (or minor for `0.x` releases) version as Pest core.
