+#### Details per each provider <a name ="details-per-each-provider"></a>
+
+* For Google OAuth to function correctly, the `oauth_redirect_uri` in application's configuration must exactly match the `Authorized redirect URIs` specified in the Google API Console. 
+
+* For GitHub to redirect correctly, set the `Authorization callback URL` to the login page of CodeChecker. This ensures proper processing of the authorization. Additionally, set the homepage URL to the homepage of CodeChecker.
