Site Upload HostGator

I need my site setup with the WordPress quick install and need guidance on how to do it. I don’t want to move files around or databases. Just as simple as possible. (I already have WordPress installed on my computer.)

I need connected my domain and my finished site. I want to be able to update my site from my WordPress dashboard on my computer as I do now.

Also, my WordPress is a multisite which I don’t want to mess up.

I have this link but still a bit confused.
