Stock by Attribute installation help!!

I have read the installation instructions for Stock by Attributes v4.7ajax. I am at a total loss. I'm listing the instructions below, and if anyone can 'dumb it down' for me, that'd be awesome!

Installation

Create a new database table and a new configuration switch by running the 'stock_attribute.sql' via Admin->Tools->Install SQL Patches. If you prefer to use another method to create this table, you will need to edit the file if you use a prefix such as "zen_" for your tables.

Prepare the package for upload to your server by renaming the following folders to match your template name: includes/modules/YOUR_TEMPLATE and includes/templates/YOUR_TEMPLATE.

If you are installing onto a new install or upgrade of Zen Cart 1.3.5 or later then with most good FTP programs (such as FileZilla) you can simply drag and drop the admin and includes directories into the root directory of your site. The files are already arranged in their directory structure.

Unfortunately, that's about as simple as they can be.

Do you have an FTP program, like Filezilla?

Did you install Zencart manually, or through your host's automatic installer?

Have you created your CUSTOM template?
