We welcome contributions from the community to every aspect of the documentation.

  • Found something not up-to-date? Open an issue or create a PR.
  • Typos and other small text enhancements? Create a PR.
  • Want to add something new or make larger changes? Great! Please open an issue and let us discuss this.

Typically, each of the different documentation projects contain links (and so does this document, in the table-of-contents pane) to edit and improve them. Additionally, below we provide you with the necessary information to get started.
