   - Create an OWL file 'owl/living_room_objects.owl' in the 'livingroom_map' package using Protege. Import the knowrob.owl ontology from the ias_semantic_map package and create a few object classes as subclasses of the existing classes. Search for 'FurniturePiece', 'FoodVessel', 'BookCopy', etc as starting points.
   - Create another file 'owl/living_room_map.owl' that imports 'owl/living_room_objects.owl'. Open this file with the [[http://www.knowrob.org/doc/semantic_map_editor|semantic map editor]] and create instances of a few objects (e.g. a 'Table', two 'Cupboard's and a 'Sofa-PieceOfFurniture').
-  - Remember to create *.owl.in files from the OWL files in which the global include paths are replaced with placeholders as described [[http://www.knowrob.org/doc/create_your_own_knowrob_package|here]].
+  - Remember to create *.owl.in files from the OWL files in which the global include paths are replaced with placeholders as described [[http://www.knowrob.org/doc/create_your_own_knowrob_package|here]] and set up your CMakeLists.txt accordingly. The *.owl.in files are the ones that should be in the repository, not the *.owl files that are generated from them.
+  - Compile your packages using rosmake and make sure the *.owl files are correctly generated.
+  - If everything builds fine, add the changed files to the repository and commit them using a meaningful commit message.
+  - Load KnowRob with the newly created 'livingroom_map' package as argument. The system should load without any errors, and you should see two lines saying that living_room_objects.owl and living_room_map.owl have been parsed.
+  - Try to visualize the newly added objects and ask for their positions and properties.
+  - Start with developing the chat client, starting from the test client in json_prolog/examples/JSONPrologTestClient.java (or one of the other example clients in whatever language you prefer). The json_prolog node offers a ROS service through which queries can be sent, the equivalent to the normal interactive Prolog shell that you have used before, just through ROS.
+  - Extend the client such that it interprets simple natural-language commands like "Where is the sofa?", generates a Prolog query to read the (x,y,z) position of the sofa, and creates a simple response like "The sofa is at 0.2, 2.4, 0.3".
