Hi, I'm planning to start my first site soon but I want to implement a custom coming soon template I purchased (not a Prestashop module) with separate html, css, js, etc folders and files. Being a newbie, I'm not sure how best to approach this as I'm concerned that there may be folders and files with the same names in the standard Prestashop install on the server and I would imagine that would confuse things. I've talked with the hosting site and they've suggested that there may be a number of different options for me, most of which seem a bit convoluted to me. Just wondering what experienced folks like yourselves might suggest as the best approach. Thanks in advance!
