# Usage and Configuration

Sometimes, running Black with its defaults and passing filepaths to it just won’t cut it. Passing each file using paths will become burdensome, and maybe you would like Black to not touch your files and just output diffs. And yes, you can tweak certain parts of Black’s style, but please know that configurability in this area is purposefully limited.

Using many of these more advanced features of Black will require some configuration. Configuration that will either live on the command line or in a TOML configuration file.

This section covers features of Black and configuring Black in detail:

- The basics

- File collection and discovery

- Black as a server (blackd)

- Black Docker image
