I seriously doubt the additional "--" are the real source of the
confusion in this case.

However, feel free to remove it if you think it's more confusing than
helpful. Just open a ticket for me to update the getting started guide

only remove its documentation but not the implementation) for backward
compatibility and so people finding old web pages and suchlike will not
fail to build too early on :-)
