# OPTIONS
*-C, --config* <path>
The config file to use. By default, the following paths are checked:
_$HOME/.swaylock/config_, _$XDG\_CONFIG\_HOME/swaylock/config_, and
_SYSCONFDIR/swaylock/config_. All flags aside from this one are valid
options in the configuration file using the format _long-option=value_.
For options such as _ignore-empty-password_, just supply the _long-option_.
All leading dashes should be omitted and the equals sign is required for
flags that take an argument.
*-c, --color* <rrggbb[aa]>
Turn the screen into the given color. If -i is used, this sets the
background of the image to the given color. Defaults to white (FFFFFF), or
