+Hello and welcome! This folder has been automatically generated by `@changesets/cli`, a build tool that works

+# Release Process
+
+This repository uses [Changesets](https://github.com/changesets/changesets) to manage versions, create changelogs, and publish to npm.
+
+## Workflow
+
+1. Make changes
+2. Add a changeset using `pnpm changeset`
+3. Commit and push
+4. Create a PR
+5. When the PR is merged, a "Version Packages" PR will be automatically created
+6. When the "Version Packages" PR is merged, packages will be published to npm automatically
+
+## Creating a changeset
+
+To create a changeset, run:
+
+```bash
+pnpm changeset
+```
+
+This will:
+1. Ask which packages you want to release
+2. Ask what type of version change it is (major, minor, patch)
+3. Ask for a summary of the changes
+
+This will create a markdown file in the `.changeset` directory that should be committed with your changes.
+
+## CI & Release Process
+
+The CI/Release process is streamlined into a single workflow:
+
+1. All PRs and main branch commits trigger the CI process (build, type check, lint, test)
+2. When changes are merged to the main branch, the same workflow also:
+   - Creates or updates a "Version Packages" PR that includes version bumps and changelog updates
+   - When the Version Packages PR is merged, automatically publishes packages to npm
+
+## Manual release
+
+If you need to do a manual release:
+
+1. Run `pnpm changeset version` to update versions and changelogs
+2. Run `pnpm build` to build all packages
+3. Run `pnpm changeset publish` to publish to npm
