How can I make a good features file on this ?

[Roelof Wobben]

Hello,

I like the idea of spinach more then cucumber.

In both im a very beginner.

So I wonder how I can make a  good features file on this case.

What I want is to add a new client

So I think this can work :

Feature: add a new member
  In order to add a new client

  As a staff member
  I want to see a message that the client is added. 

  Scenario: add a new member
    Given I have a person who wants to be a client
    When I add the data of that client  

    Then the output schould contain the new client-code.

Or can this be improved.
