When it comes to adding third-party launchers on the Steam Deck, NonSteamLaunchers is generally my go-to. This awesome script will automatically install each launcher, get the newest version of Proton GE, and add it to Steam, along with a controller configuration specifically for it. Over the past few months, we have seen some great improvements to make it easier to use, but with today's update, we see a couple of major features getting added, including scanning and adding non-Steam games to Steam.
You can check out our guide on how to use NonSteamLaunchers so you can get these all for yourself!

Automatic Game Scanning for Epic and Ubisoft
The biggest part of this update is easily the ability to now scan and add games to Steam that aren't downloaded from Steam. For now, this only supports Epic Games and Ubisoft Connect, but there are going to be more coming soon! This process is automatic, and these will show up once you either restart the device or go back to Game Mode from Desktop. It will also get rid of the games from your library if they are uninstalled.
Artwork Galore + Multiple Steam Account Support
We also have more artwork! This means that everything added will automatically have artwork, whether it is a game, launcher, or a streaming service supported by NonSteamLaunchers. We also have support for multiple Steam accounts, which is really nice, but it may not be working just yet.
There were also some bug fixes and the addition of the VK Play launcher, all of which are nice touches. You can view the full changelog below. As stated above, check out our guide on how to use NonSteamLaunchers so you can download and install the launchers you want to use!
