 Prettier uses [cosmiconfig](https://github.com/davidtheclark/cosmiconfig) for configuration file support. This means you can configure prettier via:
 
 - A `.prettierrc` file, written in YAML or JSON, with optional extensions: `.yaml/.yml/.json/.js`.
+- A `.prettierrc.toml` file, written in TOML (the `.toml` extension is *required*).
 - A `prettier.config.js` file that exports an object.

 ## Configuration Overrides
 
 Prettier borrows eslint's [override format](http://eslint.org/docs/user-guide/configuring#example-configuration). This allows you to apply configuration to specific files.
