A starting point for crafting living style guides. You can clone, fork, or download the repo from GitHub. Once you have the files for Style Guide Boilerplate, you'll create a directory on your site for them. Style Guide Boilerplate is currently PHP based so you will need a server that supports PHP. Upload the files from the GitHub repo to your newly created directory. In the head of Style Guide Boilerplate are custom styles for the boilerplate itself.
YADS is a clone of the documentation system that PHP uses for its API.
Since PHP doesn't have it in a nice package for everyone and their twin to download and install (at least none that I can see), I figured I will just recreate it.
