+Pling-Store is a Content Management App for OCS-compatible websites like opendesktop.org, gnome-look.org, etc.
+It allows to download and install applications, desktop themes, icon themes, wallpapers, or mouse cursors 
+under various desktop environments using the "Install"-button.
+
+Currently supported are these desktop environments:
+KDE Plasma, Gnome, XFCE, Mate, Cinnamon, Budgie, LXQt, Elementary and Enlightenment.
+
+## Usage
+
+Using the Appimage package format, it should work on any distro like Ubuntu, Debian, Arch, Suse, Redhat and many more.
+
+
+### Best with AppImageLauncher
+
+If you never used an Appimage before, we recommend this tool to make AppImages run, install/uninstall and update on your Linux OS:
+https://www.pling.com/p/1228228/
+
+*Please see if AppImageLauncher offers native packages for your distro, if not, you may request it in the issue section.*
+
+After installing AppImageLauncher, you can simply Double-Click on the Pling-Store Appimage to run or install it.
+
+
+###  Manual Run
+
+To try the Pling-Store without installing, you can simply [make it executable](https://youtu.be/nzZ6Ikc7juw?t=78) and (double-)click on it. 
+
+## Development
+
+The Pling-Store is a regular electron app plus the [ocs-manager](https://git.opendesktop.org/akiraohgaki/ocs-manager/). The first acts as a presentation 
+layer and the second is the one who handles the intallation of the different products.
+
