Multi store on a different domain

[waterp]

Hi, I'm testing multi store features but I'm not able to understand some things.
I'd like to have a second store on a different domain but I don't know how to do it.

I don't understand this part.

It seems that I don't need a second installation, isn't it?

In case you want to use a different domain name for your supplemental shop rather than a subdomain/subfolder, you must configure your domain to point to the folder where PrestaShop is located. The URL rewriting is then done by PrestaShop itself.

Alternatively, you can create an alias for your domain name that redirects to the absolute URL where your installation of PrestaShop is located. The way to achieve this depends on the control panel and options that your hosting company provides you with: "Alias" for Plesk, "Forward" for CPanel, "Aliasdomain" for ISPConfig, etc.

On the second domain (on a different server) I set the domain in this way in the past. Is this the part where the guide asks to modify to point to the first installation?
