I'm doing some work on a webpage, meaning I gotta modify a few things. As a result of this I installed apache and all the things that come associated with it, and also installed Joomla, and I got everything running well. 

My problem is, I need to make apache run this website locally, so I downloaded the public\_html folder from the FTP server on my website, but I have absolutely no idea how to implement the website in order to make it run on apache.

I've read a few guides, but they all tell me how to create a new website instead of helping me host a website already done.
