Installing EP is one of the easier mods...
There are TWO folders:
ADMIN
TEMP
Just re-name ADMIN to your admin folder's name, and then FTP both the admin and the temp folder to your server. Do not worry about any of the "loose files" under those two folders. They stay on your machine.
(Make sure that in your FTP, you can see your admin*** folder - because you must make sure the FILES inside the EP admin folder get sent to the correct location).
Takes 20 seconds to complete - maybe less.
THEN, in your ZC admin panel, go to TOOLS and click Easy Populate.
When opening for the first time EP will ask you to click a configuration link (top of screen). Click that.
THEN... go to Configuration Menu and open EP configuration. The only setting you need bother about is the DATE formatting. Leave the rest.
I have a TUTORIAL in the WIKI on using Easy Populate.
