# Example config

This example config lists all of the [rules](rules.md) and their primary options. You can remove ([or turn off](configuration.md#rules)) the rules you don't want and edit the primary option of each rule to your liking.

You might want to learn a little about [how rules are named and how they work together](about-rules.md), to get a better idea of what each rule does.
