+    <p>
+	RetroDECK brings an environment to catalog and play your retro games directly from SteamOS and it's tailored specifically for the Steam Deck.<br/>
+	It's inspired by embedded emulation systems like AmberELEC, EmuELEC, CoreELEC, Lakka, and Batocera.
+	</p>
+	<p>
+	Powered by EmulationStation Desktop Edition, which uses RetroArch and other standalone emulators to allow you to import and play your favorite retro (and even not-so-retro) games in a tidy environment without flooding your Steam library.<br/>
+	No other software is needed as everything it's already included!
