Explain how to add pylint as a system hook

[aleb]

As described in pre-commit/pre-commit-hooks#157
using this hook runs pylint isolated from everything else.

[aleb]

I see the repo name "mirrors-pylint" but is it really a mirror repo - should I do the pull request to some other origin repo?

[asottile]

this doesn't really make sense here I'm afraid since your example doesn't utilize this repository at all

this is (fwiw) already documented on https://pre-commit.com (^F pylint)

[aleb]

If you search pylint in https://pre-commit.com/hooks.html, you get here. It might not be the best place, but it's useful. Should I leave only the warning and a generic link to https://pre-commit.com/#repository-local-hooks for "the alternative"?

[asottile]

yes that seems better

[aleb]

Looks ok?

thanks!
