GitHub provides a wiki-style place to add your project's documentation. You can create as many pages as you like and also grant public access to it so that everyone can edit it.
In addition, when you are the creator of a product and have users that rely on it, you will want it to be as stable as possible. Versioning helps to maintain an achievable goal. GitHub provides the right tools to release versions of your code, which in reality are just snapshots in time. Whenever you believe your project is ready to get out in the wild, whether bugs are fixed or new features are added, you can use the releases feature and deliver versioned tarballs to the world.
After finishing this chapter, you will have learned to create, edit, and maintain a wiki by providing a home for your documentation that will complement your project.
You will also learn how to create a new release out of an existing branch or tag accompanied with optional release notes...
