+You must configure the following wisemapping properties (app.properties) in order to get google authorization working
    * `google.oauth2.callbackUrl`: url where google will redirect after user authentication, tipically {frontendBaseUrl}/c/registration-google. Also, this url must be defined in google app configuration
    * `google.oauth2.clientId`: client id from google app
    * `google.oauth2.clientSecret`: client secret from google app
 
-Be sure your google app has the following scopes allowed:
-   * `https://www.googleapis.com/auth/userinfo.profile`
-   * `https://www.googleapis.com/auth/userinfo.email`
+First you must create a google application and complete all the information required by Google. Here are the most important properties.
+
+Oauth consent screen
+   * Authorized domains: wisemapping domain (ex: wisemapping.com), and you can add domains of other environments if needed
+   * Permissions
+      * `https://www.googleapis.com/auth/userinfo.profile`
+      * `https://www.googleapis.com/auth/userinfo.email`
+   * Test users: emails for testing, those can be used before the application is validated by google
   
+After that, in Credentials, you must create an `Oauth Client Id` credential
+   * Authorized JavaScript origins: list of authorized domains from which to redirect to google. Ex: `https://wisemaping.com`, `https://wisemapping-testing.com:8080` 
+   * Authorized redirect URIs: list of allowed urls to which google will redirect after authenticating . Ex: `https://wisemaping.com/c/registration-google`, `https://wisemapping-testing.com:8080/c/registration-google`
