 > [!NOTE]
 > If you are already using ROS2 with Cyclone DDS according to [ROS2 documentation on Cyclone DDS](https://docs.ros.org/en/humble/Installation/DDS-Implementations/Working-with-Eclipse-CycloneDDS.html), you don't have to install Cyclone DDS as suggested by `unitree_sdk2_python`. But do follow the rest of the instructions.
 
 Follow the instructions in [`unitree_sdk2_python`](https://github.com/unitreerobotics/unitree_sdk2_python).

+### Step 3: Configuring DIAL-MPC
 
 In `dial_mpc/examples/unitree_go2_trot_deploy.yaml` or `dial_mpc/examples/unitree_go2_seq_jump.yaml`, modify `network_interface` to match the name of the network interface connected to Go2.
 
 Alternatively, you can also pass `--network_interface` to `dial-mpc-real` when launching the robot, which will override the config.

 Follow the [official Unitree documentation](https://support.unitree.com/home/en/developer/Quick_start) to disable sports mode on Go2. Lay the robot flat on the ground like shown.
