 ## Usage
 
-### Network device enumeration
-
-When using Femto Mega and Gemini 335Le, you can use the network to connect the device.
-
-**Femto Mega:**
-
-```bash
-ros2 launch orbbec_camera femto_mega.launch.py enumerate_net_device:=true
-```
-
-**Gemini 335Le:**
-
-```bash
-ros2 launch orbbec_camera gemini_330_series.launch.py enumerate_net_device:=true
-```
-
-For more information about network device enumeration.Reference:[Network device documentation](./orbbec_camera/examples/net_camera/)
-
-### GMSL device enumeration
-
-When using Gemini 335Lg, you can use the GMSL to connect the device.
-
-```bash
-ros2 launch orbbec_camera gemini_330_gmsl.launch.py
-```
-
-For more information about GMSL device enumeration.Reference:[GMSL device documentation](./orbbec_camera/examples/gmsl_camera/)
-
-### Multi-Camera
-
-When you have multiple cameras, you can activate all of them at the same time.
