+## [auth.github]
+You need to create a github application (you find this under the github profile page). When
+you create the application you will need to specify a callback URL. Specify this as callback:
+
+    http://<my_grafana_server_name_or_ip>:<grafana_server_port>/login/github
+
+This callback url must match the full http address that you use in your browser to access grafana, but
+with the prefix path of `/login/github`. When the github application is created you will get a
+Client ID and a Client Secret. Specify these in the grafana config file. Example:
+
+    [auth.github]
+    enabled = true
+    client_id = YOUR_GITHUB_APP_CLIENT_ID
+    client_secret = YOUR_GITHUB_APP_CLIENT_SECRET
+    scopes = user:email
+    auth_url = https://github.com/login/oauth/authorize
+    token_url = https://github.com/login/oauth/access_token
+
+Restart the grafana backend. You should now see a github login button on the login page. You can
+now login or signup with your github accounts.
+
+## [auth.google]
+You need to create a google project. You can do this in the [Google Developer Console](https://console.developers.google.com/project).
+When you create the project you will need to specify a callback URL. Specify this as callback:
+
+    http://<my_grafana_server_name_or_ip>:<grafana_server_port>/login/google
+
+This callback url must match the full http address that you use in your browser to access grafana, but
+with the prefix path of `/login/google`. When the google project is created you will get a
+Client ID and a Client Secret. Specify these in the grafana config file. Example:
+
+    [auth.google]
+    enabled = true
+    client_id = YOUR_GOOGLE_APP_CLIENT_ID
+    client_secret = YOUR_GOOGLE_APP_CLIENT_SECRET
+    scopes = https://www.googleapis.com/auth/userinfo.profile https://www.googleapis.com/auth/userinfo.email
+    auth_url = https://accounts.google.com/o/oauth2/auth
+    token_url = https://accounts.google.com/o/oauth2/token
+
+Restart the grafana backend. You should now see a google login button on the login page. You can
