Import site

HI all, I exported a site I was working on to show the client how it works, how do I import it again to continue working on it. Thanks in advance for your help

You don't import sites to continue working on them, you just open the project file that you saved for that site. You cannot edit sites outside of the app and then import them back in with the same BSS functionality, all edits must be done within the app if you want to continue using the drag and drop features as well as the ability to edit settings without having to do it all manually in the code.
