 Don't modify included files directly. If you want to make changes, you have to install protobuffers tool chain and gRPC then generate the Python bindings from [`pbx/model.proto`](https://github.com/tinode/chat/tree/master/pbx/model.proto) (your path to `model.proto` may be different):
 ```
-python -m grpc_tools.protoc -I../pbx --python_out=. --grpc_python_out=. ../pbx/model.proto
+python -m grpc_tools.protoc -I../pbx --python_out=. --pyi_out=. --grpc_python_out=. ../pbx/model.proto
 ```
 The generated `model_pb2_grpc.py` imports `model_pb2.py` as a module instead of a package which is incompatible with python3 packaging system. Use `../pbx/py_fix.py` to apply a fix. This is only needed if you want to repackage the generated files.
