 ## Style Guides
 
-Every major open source project has its own style guide, a set of standards and conventions for the writing and design of code, documentations and assets. It is much easier to understand a large codebase when all the code in it is in a consistent style.
+Every major open source project has its own style guide, a set of standards and conventions for the writing and design of code, documentations and Git commit messages. It is much easier to understand a large code base when all the code in it is in a consistent style.
 
 A style guide establishes and enforces style to improve the intelligibility and communication within the project community. It ensures consistency and enforces best practice in usage and language composition.

 ### Git Commit Messages
 
 A well-crafted Git commit message is the best way to communicate _context_ about a change to the maintainers. The code will tell what changed, but only the commit message can properly tell why. Re-establishing the context of a piece of code is wasteful. We can't avoid it completely, so our efforts should go to reducing it as much as possible.
