Hey! Can you link to proper the docs, so I could verify the PR?

[robin-nitrokey]

This is specified by PEP 561.

Does it work for you? I think you are missing adding this file to the project configuration (which is suggested in the docs).

[robin-nitrokey]

Yes, it works for me. We use flit for packaging and it includes all files inside the package folder:

Data files which your code will use should go inside the Python package folder. Flit will package these with no special configuration.

Note that we don’t mention the VERSION file in there either.
