EndeavourOS

1. Install Flatpak

   To install Flatpak on EndeavorOS, you must first make sure your installation is up to date, run the following in a terminal:

   sudo pacman -Syu

   Then install Flatpak:

   sudo pacman -S flatpak

2. Add the Flathub repository

   Flathub is the best place to get Flatpak apps. To enable it, run:

   flatpak remote-add --if-not-exists flathub https://dl.flathub.org/repo/flathub.flatpakrepo

3. Restart

   To complete setup, restart your system. Now all you have to do is install some apps!

   Note: graphical installation of Flatpak apps may not be possible with EndeavourOS.
