So, I'm helping a friend to build an art-themed website where they post art and offer to sell prints. He wants me to help him to make this thing, but he's using WordPress, and I know nothing about WP's content management system, let alone the templates. I guess I COULD look up how to make a template... but our idea is to build a from-scratch HTML template based on one I already did and got working. So... now what? Can I upload a ZIP package to the site and have it publish? To be honest I don't even know how it works the normal way, I just put together a site, emailed my teacher a ZIP, and he did the trick that gets it online.
I found a page that says that WP allows FTP programs. I don't know what that is. What do I need to read about to make this work? What IS a FTP? Can't I just upload the docs to the site dropbox-style?
