-### Configuration
-
-This program uses [TOML](https://toml.io/en/v1.0.0) for its configuration. The
-configuration file is set up like this:
-```
-$ cat $XDG_CONFIG_HOME/xdg-sanity.toml
-[tools]
-browser = "firefox"
-xdg = "handlr launch"
-```
-
-The options available for `xdg` are `handlr launch` if you use `handlr(1)` and
-`xdg-open` if you use `xdg-utils(1)`.
