+     and it is highly recommended to backup your instance before upgrading. After making your backup, you can upgrade to the latest version either by
+     setting your <literal>stateVersion</literal> to <literal>20.09</literal> or higher, or set the <option>services.jellyfin.package</option> to
+     <literal>pkgs.jellyfin</literal>. If you do not wish to upgrade Jellyfin, but want to change your <literal>stateVersion</literal>, you can set
+     the value of <option>services.jellyfin.package</option> to <literal>pkgs.jellyfin_10_5</literal>.
