 ### Building the simulation environment
 
-1. Build the drivers for the simulation
-   - `cd /home/rrrobot/rrrobot_src/src/simulation_env/`
+1. Source ROS Setup
+   - `source /opt/ros/melodic/setup.bash`
+2. Build the drivers for the simulation
+   - `cd /app/rrrobot_src/src/simulation_drivers/`
    - `source build.sh`
 
-
 ### Running the simulation
 
 1. Start ros master node
    - `roscore &`
 2. Run the gazebo simulator - this will bring up gazebo with a robotic arm
-   - `gazebo /home/rrrobot/rrrobot_src/world/rrrobot.world`
+   - `gazebo /app/rrrobot_src/world/rrrobot.world`
 3. Run control and perception programs
