Hi Russ,

the "joomla root" (sorry about the typo; will fix this) means the folder in the file system (not the database) that Joomla is installed into. On a typical web server this might be something like /users/yourusername/public_html. In that folder you'll find subfolders such as administrator, cache, components, images, includes, modules, plugins, media, templates and a few others. It's where Joomla lives.

So, alongside those other folders create one called simple "geoip" (no quotes).

To create that folder, you would generally use a file manager inside your hosting control panel (e.g. cPanel), or via FTP, or with something like eXtplorer in Joomla.

Then download the latest GeoIP database from the link given, uncompress it, then upload it into that folder using the same tool that you used to create the folder in the first place.

Hope that helps,
Stephen
