Can you make some examples of minimal use of nodify, the current three examples are a bit too hard to understand for beginners. Thanks.

Hi wdc63, I'm thinking of creating another library based on Nodify that abstracts all the MVVM boilerplate. Here's a POC if you're interested: https://github.com/miroiu/nodify/tree/feature/new-blueprint

I updated the wiki in the meantime with a getting started section.
