How to authorize Steam OpenID Django?

Question

Django

Hello kite-breeders!
My question is quite complicated, so I'm asking here for help.
The bottom line is this: I'm creating a site on Django, which should have user authorization through Steam OpenID. Everything would be fine, but in Google I found a lot of incomprehensibly stated solutions without any sane documentation, and it’s impossible to reach the developers in any way. Previously, I created some sites with the most primitive authorization through Django tools, but with Steam and the OpenID provider, nothing comes out at all.
Please advise any more or less sane solutions that can suit me. I can provide one class from github, which, according to the author, is the best solution to this problem, but I can’t figure it out in any way
