Installation nouvelle

Bonjour,
Je souhaiterais faire une nouvelle installation par vos soins.

Merci.
Bien cordialement.

I'm not familiar with French so I guess you want to use Quickstart Installation service, right?

Firstly, you need to purchase this installation service first : https://www.joomlart.com/member/signup?product=25

Then submit a new ticket for Quickstart installation and provide all required information so we can install for you:
