 	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.
 	No other software is needed as everything it's already included!</p>
+  <p>
+  NOTE: Albeit RetroDECK could possibily work on every distro, it's supported only on Steam Deck.</p>

+          <li>DOLPHIN (SA): Fixed a bug where Dolphin couldn't be properly configured. If it's still misconfigured please run `flatpak run net.retrodeck.retrodeck --reset-sa` in order to reset all the standalone emulators, including Dolphin. </li>

+          <li>Removed some broken tools that will be reintroduced once fixed, including the roms moving tool. </li>
+        </ul>
+
+        <p><b>Known Issues:</b></p>
+        <ul>
+          <li>PCSX2: due to its limitation, the standalone PCSX2 doesn't have any way to set the hotkeys, so no save and load state, no quit button. In order to quit press: STEAM -> PCSX2 -> (X) CLOSE WINDOW, be aware that the state is not automatically saved</li>
+          <li>Due to a Steam limitation, external controllers and keyboard seems not to be working, expecially in the desktop mode</li>
+        </ul>
+
+        <p><b>IMPORTANT NOTE:</b>
+        At the moment the emulator configs are reset during every update, this was made because every version they may bring new configurations, please back them up if you did some manual configs.
