+### Versioning
+
+The project uses automated version bumping:
+
+- **Development builds**: Use `npm run build` (no version change)
+- **Release builds**: Use `npm run build:release` (bumps patch version)
+- **Manual version bumps**: Use `npm run version:patch|minor|major`
+- **Automatic**: All commits/merges to `main` automatically bump the patch version via GitHub Actions
+
+The workflow skips version bumps for:
+- Documentation-only changes (`.md` files)
+- Changes to `.github/` directory
+- Commits containing `[skip-version]` in the message
+
