Shall we close this one?

It might be useful to add a usage/code example to each of the trophies so that readers can have a real world reference implementation to review, that would make it easier to integrate the properties in their own projects.
We could ask the project team to add a minimum example, or we could create it ourselves.

What are your thoughts on this?
