I'm working on this very topic, so this article was timely.
There is a statement in the article: "The template parameters can be overridden as required" which may not be as simple as it sounds.
By default, a selection of parameters are available to be overridden – the DF name and connection strings, for example. But if you want to override a parameter which is not included by default, things get tricky and I'm still working through how to do it.
If you haven't even tried to resolve your issue, please don't expect the hard-working volunteers here to waste their time providing links to answers which you could easily have found yourself.
