Improve node source explanations and examples #237

Some command line examples are invalid:

Parameters are not introduced in the order they have to be passed to the command line. They should be listed in that specific order and a sentence added to mention that order matters.

Hopefully, parameters and their order can be deduced by looking at the configure method of each infrastructure implementation.
