+# Backend Google Sign On for Magento 2
+This is a Magento 2 extension that allows to authenticate into Magento 2 Admin Panel using Google Sign On services.
+
+## Installation
+Install the extension through composer:
+
+    composer require msp/module-backend-google-sign-on
+
+Once Composer finishes installing the dependencies, run:
+
+    bin/magento setup:upgrade
+
+## Configuration
+After the module is installed, authenticate into Admin Panel and go to `STORES > Settings > Configuration > SECURITY > Google Backend Sign On`.
+
+You should see the following configuation fields:
+
+![Configuration](doc/img/configuration-01.png)
+
+To fill the **Client ID** ad **Client Secret** fields, go to https://console.developers.google.com/ to create the required **OAuth client ID** credentials (read detailed instructions [here](https://developers.google.com/identity/protocols/oauth2/javascript-implicit-flow?hl=it)).
+
+As **Authorized JavaScript origins** set the base URL of the site where you are installing the extension.
+
+As **Authorized redirect URLs** set the URL of the Admin Panel.
+
+You can also define a set of domain-based rules to automatically assign a role to a user or to force a user to use the Google Sign On, as shown below:
+
+![Rules](doc/img/rules-01.png)
+
+## Usage
+Once enabled and configured, the extension adds a **Google Login** button in the sign in form of the Admin Panel, as shown below:
