 ## HOOK SYSTEM
 
-`vcsh` provides a hook system. Hook scripts need to be executable and placed
-in <$XDG_CONFIG_HOME/vcsh/hooks-available>. From there, they should be

+execute hooks that are in this directory.
 
 Hooks follow a simple format. `pre-run` will be run before anything is run.
 If you want to have more than one script for a certain hook, just append
-strings to order them. A system of `pre-run`, `pre-run.10`, `pre-run.20` etc
-is suggested. The dot it optional.
