Thanks @rghara , LGTM, I'd like to ask you to do a few minor updates, please name the application as Quarkus Github, it is actually an Oauth2 aware application, but it wiul still be a bit technical.
And if you don't mind have a callback URL like http://localhost:8080/github, since userinfo can cause some confusion due to the association with UserInfo

Hi @rghara It is ready to go now but the rebasing did not work out, I guess it is simplest at this stage to close this PR and open a new one, and I'll merge. Would you like to go ahead and replace this PR ? Note it does not fix the linked issue as a few other Renarde references remain in some other application setups there, but fixing Github instructions is important

I think I need to create a new branch all together. I will gradually replace the others as well. It takes too much time to replace all of them at once. Started creating for Google as the next change.
