I spent a good chunk of last week working through the "Getting started" guide for GCE and the Guestbook example. It seems to me it would be wise to integrate these two resources more.

Right now, the Getting Started with GCE guide has its own example to work through involving Nginx on two containers. The docs would be more maintainable if this instead linked to a universal example, (since it doesn't depend on the provider you're using,) either involving Nginx or not, e.g. the Guestbook example.
