compinit

source

The first 3 lines of of simple .zshrc is:

autoload -Uz compinit promptinit
compinit
promptinit

What it does is simply bring the functions compinit and promptinit into scope and execute them. These functions will be in scope if they're under $fpath, this will be the case if zsh if installed properly in your system.

compinit will initialize completion for the current session when called directly, in .zshrc.

zshrc complete

This is what I roll with for now. Might need to improve it someday after reading the docs and figuring out what's what.
