+Installation
+============
+
+Server-side
+-----------
+Install and enable the GA Login module.
+
+While optional, it is highly recommended to install either the Mobile Codes or
+the QR Codes module:
+* Mobile Codes, http://drupal.org/project/mobile_codes
+* QR Codes, http://drupal.org/project/qr_codes
+
+By default, the account name used with Google Authenticator for an individual
+user is the user's username @ [site name], although this can be configured
+at Admin > Configuration > People > GA Login.
+
+Client-side
+-----------
+Once the server-side installation is finished, each user will have to configure
+his or her account for use with Google Authenticator.
+
+Users will need to install the Google Authenticator app or client on their phone
+or desktop:
+* Google authenticator app for Android, IPhone or Blackberry
