 +===== Using PyCRAM =====
 +To start using PyCRAM you first need to launch the ROS launch file. This launchfile is located in the directory "launch" and is named "ik_and_description.launch". 
 +
 +The launchfile can be started with the following command:
 +<code>
 +roslaunch pycram ik_and_description.launch
 +</code>
 +
 +What the launch file does is start a ROS master, upload the robot URDF to the parameter server as well as starting the IK solver. 
 +
 +** Disclaimer **
 +At the moment you also need a knowrob node running for PyCRAM to start. This is because while importing packages some will look for the rosprolog services. You don't need a belief state, it only requires the rosprolog services to be reachable.
