+## Hud configuration
+
+MangoHud comes with a config file which can be used to set configuration options globally or per application. The priorities of different config files are:
+
+1. `/path/to/application/dir/MangoHud.conf`
+2. `$HOME/.config/MangoHud/{application_name}.conf`
+3. `$HOME/.config/MangoHud/MangoHud.conf`
+4. `$HOME/.local/share/MangoHud/MangoHud.conf`
+
+The default config file is installed to `$HOME/.config/MangoHud/MangoHud.conf` and will not be overwritten by the script.
+
+---
+
+### `MANGOHUD_CONFIG` environment varianble
+
+You can also customize the hud by using the `MANGOHUD_CONFIG` environment variable while separating different options with a comma. This takes priority over any config file.
+
+A partial list of parameters are below. See the config file for a complete list.

+| `toggle_hud=`<br>`toggle_logging=` | Modifiable toggle hotkeys. Default are F12 and F2, respectively.                      |
