Want to learn kumaoni

A bit of a back story I can speak Hindi but not read or write it, but my dad's village is near bagwalipokhar I would love to learn kumaoni, I travel to uttarakhand alot but have not learned the language as I live out of India most of my life is there any online class or class that I can go to when I'm in uttarakhand (haldwani), Thanks for any suggestions.
