Clarify usage of boolean Options

The Quick start sample in Readme.md gives the impression that boolean parameter can be specified with either a true or false value. However my attemps have given the following:

- whenever the parameter exists on the commandline the value will always be true
- omitting the parameter will set it to tits default value.
- trying to specify either True or False as value is ignored.
- having default value of true will always have the Option value set to true

Is this how it is supposed to work?
