    Issue #2: website instructions on upgrading 2.8.
    
    People not well aware of flatpak may wonder how to start GIMP. The trick
    is that there are no tricks! A flatpak should be run exactly as other
    applications on your desktop (whatever is the run method used by your
    current GUI).

         href="http://flatpak.org/getting.html";>ensure flatpak is
         installed</a> and if clicking the link still does not prompt to
         install GIMP, then manually install by command line: </p>
-    <p>
-    <code>flatpak install https://flathub.org/repo/appstream/org.gimp.GIMP.flatpakref</code>
-    </p>    
+        <p>
+        <code>flatpak install https://flathub.org/repo/appstream/org.gimp.GIMP.flatpakref</code>
+        </p>
+        <p>
+        Once installed, it will be made available exactly the same way
+        as other applications (menus, desktop overview, or any specific
+        application launch process used by your desktop).
+        <br/>
+        If this is not the case, we suggest to report a bug to your
+        desktop or distribution asking for proper support of flatpak. In
+        the meantime, you can still run it by command line (not as the
+        recommended method, only a workaround):
+        </p>
+        <p>
+        <code>flatpak run org.gimp.GIMP//stable</code>
+        </p>
         <h3>Systems without flatpak support</h3>
         <p>
             GIMP can also run on Solaris and is available for the BSD family of systems such as FreeBSD and 
OpenBSD.
