-       1. Add the new file new_class.cc to the ./src/Makefile.am
-       2. Add the class identifier to ./src/class_list.h eg. CL_NEW_CLASS
-
-      Advanced Topics:
-      - if you want to let your object be managed via the ObjectManager make sure to read
-        the object_manager.h header comments. You will use this most certanly only if you
-        make many objects of your class, like a weapon bullet.
