Review and annotate all existing content to indicate whether it is basically up-to-date, needs updating, is completely outdated, or should be retired (in favor of some other set of documentation).

Ensure contributing guidance is all up-to-date (README, Klipse, etc).

Figure out a better way to provide a table of contents/indices/etc to improve navigation. Add site search?

Gather a list of beginner-focused documentation that clojure-doc.org should try to provide.
