README needs to document what file format coverage is expected in, and how the search for coverage files works about codecov-action HOT 5 OPEN

Please accept my apologies. I'm not asking you, I'm joining you in the increasingly vocal chorus of voices who don't know what files are selected by default and would love to be told.

Thanks for response!

Default file patterns can be found here

...this seems to show how supplied paths would be regexp-processed ... but not what the default search locations for files/dirs is?
