The Codex may provide the information needed, but it is extremely cumbersome with hundreds of pages with only one tiny bit of information per page. And there is no navigation to go from one subtopic to the next in logical order. There is nothing one can read through easily to familiarize oneself with WordPress. Using the Codex this would require many hours. And finding a particular bit of information is like finding a needle in a haystack.
Has anyone put WordPress documentation, such as a PDF manual, in a more user-friendly format?
