I've tried reading through this, and I'm not sure exactly I understand where I'm supposed to install it to make this work.

I have a layout that's pending approval from my client (the temporary url is http://silent-asylum.net/gprf ) and it's a tables layout that is broken up with SSI. Assuming I'm a moron, can anyone tell me where to put the zencart installation (will it still embed if it's in a folder?) and give me moron-friendly step-by-steps? I really appreciate it.
