+# Release Process
+
+This repo uses [Changesets](https://github.com/changesets/changesets) for versioning and publishing.
+
+```bash
+pnpm changeset   # Create a changeset for your changes
+pnpm release     # Build and publish (CI handles this automatically)
+```
+
+Before committing, run the repo checks:
+
+```bash
+pnpm format
+pnpm check:ci
+```
+
+## Creating Changesets
+
+When making user-facing changes, create a changeset file in `.changeset/`.
+
+1. Use the filename convention `<random-word>-<random-word>-<random-word>.md`
+2. Format the file like this:
+
+```markdown
+---
+'@storybook/addon-webpack5-compiler-swc': patch
+---
+
+Short description of what changed.
+```
+
+Use `patch` for fixes and maintenance, `minor` for backward-compatible features, and `major` for breaking changes.
