What kinds of samples are you looking for? I'd be happy to contribute some simple ones

what is the intention and scope of examples in the documentation? is it defined how examples complement the documentation?

@adg Have a moment to answer @marcellanz's question? Thank you!

@marcellanz, examples are documentation. Some people prefer to learn by reading code instead of reading words.

The package now has 8 examples, so perhaps this could be closed as fixed?
