+## Branding

+```
+
+### Properties
+
+| Name | Type | Required | Default |
+| ---- | ---- | -------- | ------- |
+| show | bool | no | true |
+| name | string | no | Glance |
+| short-name | string | no | G |
+
+#### `show`

+
+#### `name`

 ## Theme
 Theming is done through a top level `theme` property. Values for the colors are in [HSL](https://giggster.com/guide/basics/hue-saturation-lightness/) (hue, saturation, lightness) format. You can use a color picker [like this one](https://hslpicker.com/) to convert colors from other formats to HSL. The values are separated by a space and `%` is not required for any of the numbers.
