A wiki is not adequate documentation and I hate this trend of making documentation HTML only. Not everyone uses or even can use a web browser. GNU software has this great tool called Texinfo which lets you write a proper book-sized documentation with proper table of contents, chapters, and indexes. You can generate HTML, PDF, and most importantly info files. You can read info files in your terminal, in Emacs, or even in Vim (wrote a plugin for that).
