Using Revolution Slider with Squarespace

I haven't worked with Revolution Slider but I have adapted other JavaScript utilities to work with Squarespace. 

If you have non minified code it's relatively straightforward, though can take some time,  to go through the code and swap out all references to /assets/ /css/  /fonts/ and replace them with /s/.  That sets the code to expect everything to be in one folder.

You should now move everything from /assets/ /css/  /fonts/ into a single directory with your script and test it locally. If it all works you should be good to upload all of the files to the Squarespace site. This can be time consuming because you need to upload the files one at a time. 

Another option, if you are working in Squarespace 7.0, is to work in developer mode, where you have the flexibility to upload folder structures.  This comes with a downside - your template is effectively locked the moment you engage developer mode - but it means there's no hassle in modifying folder structures.
