+- Import the projects into Eclipse. You can leave out de.prob.releng.  At this point Eclipse will complain about errors, the reason is that the target platform (i.e., Rodin) hasn't been setup yet).
 
 - Open the file prob_target.target from the de.prob.core project and click on "Set as Target Platform". Grab a coffee. 
 
+- After the target platform was installed and the workspace has been compiled you can run the project as an Eclipse application (use org.rodinp.platform.product as the product in the run configuration)
