We generate a new application according to a standard template in the studio. For Facebook, it is enough to register the application on Facebook, get the appId, appSecret, substitute them in the string with the string "app.usefacebookauthentication(appid: "", appsecret: "");" in StartupAuth. For the rest, we install the KatanaContrib package and write similar lines.
