     Notes
     -----
     'from_model_name' is used to create a new model referencing to an
     existing computation object. For example, when the same phase's signal
     is observed in multiple profiles, 'from_model_name' allows the refinement
     backend to modify the same structure across multiple profiles.
+
+    Exactly one of 'structure_file_path', 'from_model_name', or 'code'
+    must be provided.
