The second item `csharp.ascii` is the name of the file containing the ascii logo: this file has to be placed in the _./resources_ folder (more info below). Then we have the colors used to customize the look of the ascii logo when displayed to the screen. The last item `c#` is only required if the Enum name `CSharp` doesn't match the display name `C#` and is used as an input for `-a, --ascii-language <LANGUAGE>` - by default we take the Enum name in lowercase.
