+## Creating a release
+
+This repo uses [changesets](https://github.com/changesets/changesets) to manage
+versioning and changelogs. This means you shouldn't need to manually change of
+the internal package versions.
+
+Before opening a PR, run `yarn changeset` and follow the prompts to describe the
+changes you've made. This will create a changeset file that should be committed.
+
+As changesets are committed to the `main` branch, the [changesets github
+action](https://github.com/changesets/action) in the release workflow will
+automatically keep track of the pending `package.json` and `CHANGELOG.md`
+updates in an open PR titled `chore: version packages`.
+
+Once this PR is merged, the release workflow will be triggered, creating new
+tags and github releases, and publishing the updated packages to NPM. **These
+PRs should be carefully reviewed!**
