This document discusses various topics related to developing Ruby, including Ruby core policy and development process. It provides guidance on how to properly submit issues and pull requests to the Ruby core team, such as using Redmine for reporting issues rather than Twitter or blogs, and providing a clear use case and sample code. It also outlines the Ruby release planning process.
