 ## Use V4L2 backend
 
-To enable the V4L2 backend for the Gemini2 series cameras, follow these steps:
-
-1. The Gemini2 series cameras support the V4L2 backend.
-2. Open the `config/OrbbecSDKConfig_v2.0.xml` file.
-3. Set the navigation option to `LinuxUVCBackend`.
-4. Change the backend setting to `V4L2`.
