+## Entity `create` methods
+
+Because we need to have empty constructors in our entity classes for TypeORM to work, the actual constructor is a separate `create` method. These methods should adhere to these guidelines:

+- Only require the non-optional properties of the corresponding entity
+- Have no optional parameters
+- Have no lists which can be empty (so probably most of them)
+- Should either return a complete and fully useable instance or return a Pick/Omit type.
+- Exceptions to these rules are allowed, if they are mentioned in the method documentation
