[keycloak-user] Oauth2 Identity Provider

Hi everyone, I undersand Keycloak dos not Jahve a generic Oauth2 provider: https://issues.jboss.org/browse/KEYCLOAK-3187 https://issues.jboss.org/browse/KEYCLOAK-8244 I believe this makes sense since the spec is pretty broad, However, I think it would be a huge help to include in the docs how to create/add custom Oauth2 Identity provider. Are there any examples, which one of the existing provider would be a good starting point? Thanks!
