How to test installation?

[mkorostoff]

Problem/Motivation

It is not clear from the current README what functional goal this is meant to accomplish. (See error/solution #10 in my previous issue thread). Once you successfully install this, it is difficult to know what should happen next. More generally, it is difficult to know what this does in a material, concrete way.

Proposed resolution

Expand the current readme file to include the following:

• Screen shots of a system which has successfully installed this project (e.g. http://i.imgur.com/RXDFWzb.gif).
• Instructions for verifying that installation succeeded (e.g. "If you give the command ABC and get the response XYZ then congratulations, boot2docker-vagrant has been successfully installed).
• An example real-world use case.
• A more detailed "What Is This?" section.
