+## Configuration Files
+gau automatically looks for a configuration file at `$HOME/.gau.toml` or`%USERPROFILE%\.gau.toml`. You can specify options and they will be used for every subsequent run of gau. Any options provided via command line flags will override options set in the configuration file.

+An example configuration file can be found [here](https://github.com/lc/gau/blob/master/.gau.toml)
