Organize content into four quadrants

[jzelinskie]

Divio has a fantastic bunch of content about how to structure documentation which is used in many places such as the Django docs:

• https://docs.divio.com/documentation-system/
• https://www.youtube.com/watch?v=t4vKPhjcMZg

The gist of it is that content needs to be in one of 4 forms or else it'll all blend together and be difficult to understand and maintain:

• Tutorials
• How-to Guides
• Discussions
• Reference
