 GeoIP Module
 ============
 
+Handles looking up an IP address' country. By default this is done by executing
+the geoiplookup command. However, it is also possible to use IP database tables
+from MaxMind (http://www.maxmind.com/app/geoip_country) when this option is 
+unavailable.

+Installation Instructions
+-----------------------------------------------
+- Find out how to add modules to SS and add module as per usual.
+- If your server has geoiplookup, and the exec() function hasn't been disabled,
+  then this is all that you need to do. Otherwise, you will have to download and
+  setup the MaxMind IP country databases
+
+Installing and Using MaxMind's Database Files:
+- Download the databases (both IPv4 and IPv6) from MaxMind. They offer both a 
+  commercial version (http://www.maxmind.com/en/country) and a free version 
+  (http://www.maxmind.com/en/geolite)
+- Unpack these databases, and place them somewhere on the server within the
+  Silverstripe directory structure
+- Add the following line to your mysite/_config.php:
+  GeoIP::setGeoIPDatabases('path/to/GeoIP.dat', 'path/to/GeoIPv6.dat');
+  You will have to replace "path/to" with the path to the two database files 
+  relative to the Silverstripe base directory
