Website Outline

In an effort to be the most useful website possible, I strongly believe that we need wrangle all of our content into a coherent structure. There are many potential benefits to having a textbook-style outline.

• The website will be more approachable and useful to the people who are not themselves writing it
• We will avoid duplicative content
• We will more easily see what concepts are missing.

I have proposed an outline below. I invite comments and revisions.
