Framework7 v4 -> v6

I build an app a while back in V4. It works.
Trying to update it to V6.

All I want is the CSS and the .JS files. But it seems I have to go through this big build process using NPM? I’m lost.

I just need to replace this.

link rel=“stylesheet” type=“text/css” href="./js/vendors/framework7/4-4-10/framework7.bundle.min.css"

and this …

script type=“text/javascript” src="./js/vendors/framework7/4-4-10/framework7.bundle.min.js"></script

What do I do?
Thanks in advance

Ok. Following the migration guides; v4->v5 and then v5-v6 it works.
Some tweaking to do but it goes.
