 #### How can I install Nheko nightly?
 
-I use the nightly flatpak which is easy to install for all users:
+I use the nightly flatpak which is easy to install for all users as you
+just add the nightly repo (3rd command) and install it (5th command).
+However below there are a few extra steps in case of weird systems:
+
+_Note that `#` means a command and it's there just to explain what is being
+done, not actually entered into a terminal._
 
 ```bash
+# The dependency KDE Platform is in Flathub and very clean installations of
+# flatpak from some distributions may not have it by default...
+sudo flatpak remote-add --if-not-exists flathub https://flathub.org/repo/flathub.flatpakrepo
+# ...or if they have it by default, at least older Fedora versions disable it
+# by default.
+sudo flatpak remote-modify --enable flathub
+# This actually adds the Nheko nightly repo on your system
 sudo flatpak remote-add --if-not-exists nheko-nightly https://nheko.im/nheko-reborn/nheko/-/raw/master/nheko-nightly.flatpakrepo
+# If the Nheko flatpak doesn't appear anywhere, this equals `sudo apt update`
+# or `sudo dnf check-update` etc.
+sudo flatpak update --appstream
+# And this command actually install the nightly flatpak.
 sudo flatpak install nheko-nightly im.nheko.Nheko --assumeyes
 ```
