+# Changesets

+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)
+
+We have a quick list of common questions to get you started engaging with this project in
+[our documentation](https://github.com/changesets/changesets/blob/main/docs/common-questions.md)
