+## Releasing
+
+When releasing a new version of the SDK:
+
+1. Update the version number in `pkg/onelogin/version.go` following semantic versioning:
+   - MAJOR version for incompatible API changes
+   - MINOR version for backwards-compatible functionality additions
+   - PATCH version for backwards-compatible bug fixes
+
+2. Commit the version change:
+   ```shell
+   git add pkg/onelogin/version.go
+   git commit -m "Bump version to x.y.z"
+   git tag vx.y.z
+   git push origin main --tags
+   ```
