+# 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 the changesets repo](https://github.com/changesets/changesets).
+
+## Adding a changeset
+
+When making changes that should be released, run:
+
+```bash
+pnpm changeset
+```
+
+This will guide you through creating a changeset file that describes your changes.
+
+## What is a changeset?
+
+A changeset is a piece of information about changes made in a branch or commit. It holds three bits of information:
+
+- What packages need to be released
+- What semver bump type each package should have (major/minor/patch)
+- A summary of the changes (used in changelogs)
