+# Releasing New Rez Versions
+
+If you are a collaborator and have push access to master, these are the steps to
+follow to release a new version:
+
+1. Make sure that the version in `utils/_version.py` is updated appropriately.
+   Rez uses [semantic versioning](https://semver.org/).
+1. Before pushing your branch, update `CHANGELOG.md` to describe the changes. Follow
+   the existing structure. The PR for the merge appears in square brackets in the
+   title (eg `[#552]`); since this PR doesn't exist yet, just leave `[#XXX]` as a
+   placeholder.
+2. Push your changes, and create a PR to master. In that PR's description, copy
+   the markdown you added to the changelog for this release. Change only the title
+   - just put the version number there.
+3. Once approved, merge to master.
+4. In master, go back to `CHANGELOG.md` and update the PR number appropriately.
+5. Run tag.sh. This tags the git repo with the version in `utils/_version.py`.
+6. Do a `git push` to push changelog update, and a `git push --tags` to push the
+   new tag.
+7. Goto [https://github.com/nerdvegas/rez/releases] and create a new release. Use
+   the changelog markdown as the starting point, and format appropriately (look
+   at existing release notes to see what to do).
+
+## Example Changelog Entry
