 ## How to start working
 
+1. Install the software:
+
 ```sh
 cd ~/Documents
 git clone https://gitlab.lrz.de/robocupss18-blue3/kick-it.git
 cd kick-it
 setup/install_ros.sh
 setup/install_nao_ros.sh
-# Work!
 ```
+
+2. Check if ROS is working properly by typing `roscore` and finishing it with
+`ctrl-c` if it doesn't throw errors.
+
+3. Check if NAOQi binding for Python works by launching Python and running there
+`from naoqi import ALProxy`. The installation was successful if it imports
+without errors. You can finish Python with `ctrl-d` then.
