Contribution guidelines can be found here (TODO).

This issue can be used for any questions (Discord is good place as well).

When starting working on a new module, you can tweak the ignore_errors value in the mypy.ini configuration file:

manim/.mypy.ini

Lines 4 to 6 in c6450b2

	# ignore most files; should be checked once proper types have been implemented
	[mypy-manim.__main__]
	ignore_errors = True

Happy to help here 😊.

Nice, #3086 will bring some typing guidelines, though I still need to add more info I guess. Once merged, I'll review the typed modules individually. Feel free to tell which module you'd like to work on (after #3086 gets merged)

Planning on bringing the typing docs up to date when I have time :)
