Maybe pre-commit needs "a better way" of configuration.  Even just better docs or something.

```
$ pre-commit list

  white_space          # check for trailing white space
  console_log           # check for console.log in JS
  debugger               # check for debugger calls in Ruby
  ...

  Run this to configure pre-commit..

  $ git <whatever the pre-commit config command is>

```

Something like that would help people configure it for each repo.

Thoughts?
