Z-Shell completion system introduction: "Zsh's completion system (compsys) is one of the most praised and one of the most complex parts of the shell. That's true for users, as well as developers.
People asking for gentle introductions hit the `#zsh' IRC channel on freenode every once in a while; often enough that we added a question about it to the wikifaq (question 15 at the time of writing). The complaint is usually, that `zshcompsys(1)' and `zshcomwid(1)' are dense and dry to read and that they lack a general overview of how the system works."
