This startpage is the official usage demo of the @startpage library.
A startpage with a generic layout and many settings to modify the appearance.
Currently too lazy to write a real documentation here, if you have any questions, no matter if it is about @startpage, any usage of it here or this project in general, feel free to write an issue :)
The above shown themes are available as backups in /themes. Download the json and import it via the startpage.
