Best practise?

I’m new to wordpress theme and roots.
So I’m wondering if there’s any best practice for roots? Like for example, how we should extend the theme or what files are we not supposed to modify etc?

Like for example, http://roots.io/roots-101/ says its ok to modify lib/, are there any that we shouldn’t modify at all?

Roots is built in a way where you are supposed to edit at will. Anything you want :smile:

I see. Thanks. Will do that then. :smile:
