Is there an RGB "Hello World" guide?

At this moment you can play around with RGB either using a CLI+RGB Node or using Bitcoin Pro (both through CLI or as a UI on your desktop). Here you can see many links with demos. For example these ones: - RGB Beta Demo - Bitcoin Pro demo Corresponding repositories are mentioned in the videos and the descriptions of them: - Bitcoin Pro - RGB Node NB! Currently we are preparing a new release of RGB (still not the 'production' one), so some things may work not in a totally smooth way.
