Accesing CRM Online from SharePoint Online

I am contemplating adding some CRM data to display, and possibly enter/update in our instance of SharePoint 2013 online in Office 365.  So the user would be in SharePoint looking at CRM data and could interact with it.

Any resources / blogs / books out there that might cover this topic?  I'm a newbie to SP development, but have done extensive development (C# Plugins, JS, etc.) in CRM.

Thanks!
