I've started working with igniteui-angular and was not sure where the appropriate place to ask questions would be.
Julie,
To begin with Angular and IgniteUI, you should start with Craig's blob post where we announce that AngularJS support for Ignite UI is available as a preview:
Ignite UI + AngularJS: Now in Preview
Within the post there are links to the available directives. You can also provided feedback on GitHub for each of the individual directives.
Let me know if you have any questions.
