 # Docker Image for Virtual RobotX
 
 ## How to use
-
+Firstly, run wamvtan/vrx
+```bash
+docker run -it wamvtan/vrx /bin/bash
+ros2 launch vrx_gz competition.launch.py world:=stationkeeping_task headless:=true urdf:=/home/config/wamv_target.urdf
+```
+Next, run another docker_image wamvtan/dev_container which includes our autonomous system.
 ```bash
-docker run wamvtan/vrx
+docker run -it wamvtan/dev_container /bin/bash
+ros2 run vrx_bridge vrx_bridge_node&
+ros2 launch navi_sim navi_sim.launch.py&
 ```
 
 In default setting, you can publish/subscribe these topics.
