Re-locating entire blog to root of domain

Hi, when I set up my wordpress blog, I watched a tutorial video and the video said to make a new folder in my public_html folder called "blog". Well this is where I've been putting all my files to upload it to my blog. However, my url is I do not want the blog/ after the .com. Is there a way to take that file and put it under my root domain just .com? This might be a bit confusing, but it's the best way I can explain it as I am new. Thank you.

Move all the files/folders in the blog folder to the parent folder
If the files are currently here: /public_html/blog move them to /public_html
