defmodule Noora.Icon do
@moduledoc """
Icons in use across the Noora design system.
## Usage
The module exposes all icons in two ways:
1. As a function of the shape `<.{icon_name} />`
2. As an `icon` component that takes a `name` attribute.
```elixir
<.mail />
<.icon name="mail" />
```
## Adding an icon
Icons are automatically read and generated from the `icons` folder. To add an icon, simply add a SVG file to the folder. File names are
required to be alphanumeric. Hyphens in the file name are automatically substituted to underscores.
