XF 1.5 What is the correct way to completely remove a custom style?


I'm buying a new custom style for my Xenforo forum and once I have upgraded to the latest version of Xenforo 1.5.x I want to remove my current style completely and then install the new style.

What is the best way to do this? Do I just delete the style in the admin control panel and then delete the files from the Xenforo styles install directory?

After that I assume it is easy to just install a new style? You just do it the same way as with any style?
