 - [visp_hand2eye_calibration](http://wiki.ros.org/visp_hand2eye_calibration) for
 the [easy_handeye](https://github.com/IFL-CAMP/easy_handeye) calibration.
 
+If you have ROS melodic installed use these bash commands:
+```bash
+sudo apt install ros-melodic-tf2-geometry-msgs
+sudo apt install ros-melodic-ddynamic-reconfigure
+sudo apt install ros-melodic-image-pipeline
+sudo apt install ros-melodic-visp-hand2eye-calibration
+```
+
+Unfortunately the realsense camera needs some manual installation steps.
+But you might remove the package from the workspace and use your camera
+driver instead. The same goes for the iiwa and hand-eye-calibration
+related packages which are only required when mounting the camera on a
+robot.
