The Steam Deck is a pretty awesome gaming handheld, but the fact that it cannot easily access game services out of the box other than Steam can make it feel a bit limiting. Thankfully, there's a helpful homebrew plugin called Decky Loader that widens the gaming handheld's initial abilities. With it installed, you can easily access your library of games on Epic Games, Ubisoft Connect, and more. 

Plus, Decky Loader comes with a bunch of cool widgets and additional settings that you can install as desired. Here's how to get Decky Loader installed and enable its various features.

1. Turn on Developer Mode

10. After installation has completed, click OK. 
11. Click on the Return to Game Mode icon on the desktop.
