Every journey begins with the first step.
This web page is the first step on the way to an App Store for Linux and BSD. An App (short for Application) in this context means a mostly proprietary Application, designed for entertainment or a special task. An App is not integrated with the underlying system.
Excamples are games, ifotainment applications or an application that lets you create photo books for an printing service.
You install the Apps with the "Personal Applikation Installer" named PAPPI. This software installs an application with a single click right from the Linux App Store.
