Hi !
I'm all for more guides, but faulty overwriting of existing files is 
definitely the cause of many forum posts. There are so many clients, 
cpanels and user knowledge levels that I believe deleting first and then 
  uploading the new files has to be the way to go. And if they have a 
backup of everything then they should be fine.
