In plain English

Based on the description and topics, this is a community-driven style guide for the Ruby programming language. A style guide is a set of conventions and recommendations for how code should be written, covering things like indentation, naming conventions, spacing, and code structure, to make code consistent and easier for teams to read. This guide is associated with RuboCop, a code analysis tool for Ruby that can automatically check your code against style rules. The README does not provide further detail about the guide's specific content, how it is organized, or how to contribute.
