I have no clue

I understand the concept of FTP, but have no clue how to upload my website from my computer to the host server. The tutorial just confused me. Is there anyone that can walk me through this? thanks!

Hi, press control+l to have a full local browser, connect to remote site, arrange the windows local on left side, remote on right side, add remote to favorites.
Then drag and drop desired files from local browser to remote site.
