- Merge Community/Contributing and Engine Development into one top-level section, Contributing.
- Structure it in a way that gives equal priority to various ways to contribute, including documentation.
- Rename several articles to be more comprehensive and in line with the overall state of the documentation.
- Rewrite the guide for class reference contributions.
