+  render Mermaid diagrams in both Node.js and the browser.

+## Contributing
+
+Test fixtures are generated and verified using Linux. Rendering on other platforms may yield
+slightly different results. Don’t worry about adding new fixtures, but don’t update existing ones
+that cause CI to fail. Furthermore see my global
+[contributing guidelines](https://github.com/remcohaszing/.github/blob/main/CONTRIBUTING.md).
