You don't need to add Steam to your Steam Deck! The Steam Deck already comes with the Steam client pre-installed, allowing you to access your Steam library and enjoy all your games.
If you're looking to add additional features or customize your Steam experience on the Deck, here are a few things you can do:
- Install additional software: The Steam Deck allows you to install other software like emulators, web browsers, and productivity tools. You can find a variety of applications in the Discover Store, accessible from the Deck's home screen.
- Customize your Steam settings: You can adjust your Steam settings on the Deck to change your controller layout, adjust performance settings, and personalize your experience. You can access these settings by going to the Steam menu and selecting "Settings".
- Connect to a different Steam account: If you have multiple Steam accounts, you can easily switch between them on your Steam Deck. You can do this by going to the Steam menu, selecting "Accounts", and then selecting the account you want to use.
Remember, the Steam Deck is designed specifically for playing Steam games, so you don't need to download or install anything extra to access your Steam library.
