Hello,

I am at the same exact stage to implement a Drupal Distribution to my service provider Fastwebhost.com. Hopefully, someone will come along and guide us both on best practices. Right now I need to know how to point the URL Domain to the Commerce Kickstart 2 distribution. However, I can provide some pre-step insight. If you have not done so already, download the Acquia Dev Desktop and step up your store first. Make all of the changes and design alternation there. Why? Because its a sandbox to test and confirm operation and changes. When you are ready, migrate your final change or the drupal instance all together to your production host site. I started the opposite way and I am now back tracking which really sucks! But, I learned a lot.

Second, ask your host provider if they can provide step or example to download your Drupal Distribution and replace the default one that comes this the plan. My provider said after a number questions to just download and install the distribution and they would fix whatever breaks. Finally, the Filezilla is just a file transfer program (ftp - Okay file transfer protocol . . . wherever), but the key is to setup a ftp account with a username and password. You can generally do this on the "cPanel" which is apart of your hosting plan. Most important . . . Join a Drupal Ladder Meetup in your area. This is really helpful!

Good luck! Cheers!
