Welcome to the docs!
The Guides are the reference manuals for contributing and collaborating on the project: the Contributing guide shows how to submit issues and pull requests. The Ticket Workflow specifies the labeling, assignment, and so on for organizing tickets and the general development of the project. The Writing Guide is for writing awesome entries. Our GitHub ELI5 (Explain Like I’m 5) guide is great for newbies and for the utterly GitHub confused.
