+Hello and welcome! This folder has been automatically generated by `@changesets/cli`, a build tool that works
+with multi-package repos, or single-package repos to help you version and publish your code. You can
+find the full documentation for it [in our repository](https://github.com/changesets/changesets)

 This means running `yarn build` in the root will build all packages in parallel.
 The same goes for `lint` and `format`.
 
+## Changesets
+
+We use [changesets](https://github.com/changesets/changesets) to manage versioning, changelogs and publishing.
+This means when you contribute a PR you have to run `yarn changeset` to indicate the semver bump you are making
+and to add a changelog entry.
+
 ## Tests
 
 You can run tests for individual packages by running a Yarn workspace command.
