The question arises, how does one tell what is important enough to begin 
with?  I am trying to form a robust mental pattern for employing BDD and 
I keep running up against the tension between what I already believe to 
be necessary to provide from my prior knowledge and what point to begin 
with in features to cause this to be expressed.  The examples that I 
have found regarding how to use BDD features run the gamut from 
specifying model attributes and data normalization to macro statements 
of the form:

Given I have a web application
When I visit the application url
Then I should see a welcome message
  And I should see a sign in request

etc.

So, the question I have is:

Given I have an application design document
When I specify the design using BDD
Then I should first begin with ??????
