nuxeo 5.2.0m3 engine

Hello,

I'm hoping to get started with webengine now that it is bundled with
5.2.0 m3.  However, I've been unable to determine where the point my
browser to once Nuxeo EP is started.  

Can someone please point me in the right direction for getting started
with WebEngine in 5.2.0m3?

Thanks,
Mike
