Missing library stubs or py.typed

[LittleBread69]

Whenever PyWavefront is imported into projects like import pywavefront as wavefront or import pywavefront, MyPy gives the following error: error: Skipping analyzing "pywavefront": module is installed, but missing library stubs or py.typed marker [import-untyped].

Is there a way to add library stubs or py.typed?

Edit: Typos

If it helps, I can point to documentation's section about import-untyped.
MyPy suggests to make a PEP 561 compliant stub file.
