Requirements for running in venv? makefile outdated

[lbm-services]

Hi,
I wanted to test some changes in the source code. What is the entrypoint for running the sources?
I tried
python3 manuskript/main.py
as well as
cd manuskript && python3 main.py
with the same result:

Traceback (most recent call last):
  File "/home/hli/PycharmProjects/manuskript/manuskript/main.py", line 9, in <module>
    import manuskript.logging
ModuleNotFoundError: No module named 'manuskript'

makefile seems outdated, since there is no setup.py, see line 21:

compile:
	cd manuskript && python3 setup.py build_ext --inplace

To run manuskript you run bin/manuskript
