-# Changelog Generation
+# Steps to create a new release
+
+1. Bump version in OLM_VERSION file. Make a PR and wait until it has been merged.
+
+1. Pull change from above and make new tag with matching version. Push tag directly to this repo.
+
+1. Confirm that new images have been built here: <https://quay.io/repository/operator-framework/olm?tab=builds>.
+
+1. Run `make release` on master branch (easiest if done with a clean working directory). Make a PR and ensure all tests pass for merging.
+
+## Changelog Generation
 
 Changelogs for OLM are generated using [GitHub Changelog Generator](https://github.com/github-changelog-generator/github-changelog-generator).
 
+If the gem command is available, one can install via `gem install github_changelog_generator`. Afterward installing it may be worth modifying the MAX_THREAD_NUMBER to something lower similar to what is done here: <https://github.com/github-changelog-generator/github-changelog-generator/pull/661>. Now the changelog can be generated:
+
 ```bash
 github_changelog_generator -u operator-framework -p operator-lifecycle-manager --since-tag=<start-semver> \
     --token=<github-api-token> --future-release=<end-semver> --pr-label="**Other changes:**"
-```
+```
+
+The resulting CHANGELOG.md file can be copied into a new release created via <https://github.com/operator-framework/operator-lifecycle-manager/releases/new>.
