Follow me on Twitter (@TheTimWoodruff) to get notified of major updates to the libraries, so you’ll know when to pull down the updates!
In the Add dialog, enter a name like “sn-js-lib”, then click the “+” icon to the right, click “Attach directories”, select the folder you downloaded the libraries to, and click OK a couple of times, then you’re all set!
