+## Keeping dependencies-files up to date
+### Backend
+
+Navigate to the ./backend folder and run:  
+```
+mvn org.eclipse.dash:license-tool-plugin:license-check   
+cp DEPENDENCIES ../DEPENDENCIES_BACKEND
+```
+The first line runs the maven license tool with the parameters specified in the 
+./backend/pom.xml and produces a DEPENDENCIES file in the ./backend folder.  
+Then this file gets copied to the PURIS-project root folder under the name DEPENDENCIES_BACKEND. 
+Both files should be updated prior to any pull request.
