This is a stand-alone version of the freesewing demo.
The online demo is part of the documentation, but that is a Jekyll-based site. Which means that running your own instance is going to require some work.
If you want your own demo without the hassle, you can simply clone this into a web-accessible directory.
You should only configure the api
value in the demo.js. Default is:
var api = 'https://core.freesewing.org';
You should change that to your own freesewing instance. Note: No trailing slash
