Wappler 4 - Importing bootstrap themes

Hi,

I am very new to wappler and I have been struggling a little bit with importing a theme into wappler. I can build from scratch but it would be nice if I could figure out how to import themes with css and js.

I’ve gone over the documentation but I think it’s all out of date and isn’t really relevant anymore.

Can anyone help by giving me some basic instructions of what I should be doing?
Everything I’ve read on here and elsewhere, shows methods that are all varying and don’t seem to work anymore.

Thanks
