First, replace the domains in the source code and templates with your own (a domain is required, not just an IP). Second, copy config.ini.example to config.ini then tweak to your liking. Third, run `go build`, and fourth, run `./burgerauth`. Read ERRORS.md to see how to handle server errors.
The OAuth2 protocol should be fairly standard. Burgerauth comes with OpenID Connect discovery, and you should use that to find out the URL endpoints for the instance you are targeting, and you shouldn't really touch anything else. Burgerauth provides only authorization and not resource-delegation, and so doesn't issue refresh tokens.
OIDC is not a protocol in of itself, but rather an extension on top of a fully working OAuth2 system, made useful by the OAuth2 protocol and JWK token protocol.
