For developers, all you have to do is open the app.config file and modify three config values for your own:
  1. The DefaultAssociateTag is your Amazon Tag Id which will be used as a default or fallback value should the end user decides not to override it with hers
  2. The AwsAccessKeyId is your Amazon AWS Access Key Id. You'll need to provide yours in order to make a call to Amazon's web service API.
  3. The AwsSecretKey is your Amazon AWS Secret Key that will be used to sign the request before sending it over the wire.
