+
+This library is made to avoid custom repetitive layout code.

+## Usage

+
+The available props per layout are included as a TypeScript declarations file.
+
+## Configuration
+
+There are CSS variables that can be declared in the parent of the `*.Layout` components
+(preferably `:root`) for customizing the metrics of the layout:
+
+### `--height-topbar`
+
+Default value: `4rem`
+
+Height of the top bar widget.
+
+### `--size-menu`
+
+Default value: `4rem`
+
+Width or height of the menu, depending on the orientation it is rendered.
+
+### `--color-background`
+
+Default value: `white`
+
+Background colors of several widgets from the library.
