 ## Via flatpak (recommended)
 The recommended way to build is using flatpak, which will take care of all dependencies and avoid any problems that may come from different system configurations.
 
-First, install the required flatpak platform and SDK, if you dont have them already:
+If you don't have the flathub repo in your remote-list for flatpak you will need to add that first:
+```shell
+$ flatpak remote-add --if-not-exists flathub https://flathub.org/repo/flathub.flatpakrepo
+```
+
+Then install the required flatpak platform and SDK, if you dont have them already:
 ```shell
 $ flatpak install org.gnome.{Platform,Sdk}//41 org.freedesktop.Sdk.Extension.rust-stable//21.08 org.freedesktop.Sdk.Extension.llvm12//21.08
 ```
