Show HN: NGS – programming language intro documentation feedback wanted

I'm working on NGS for several years now. It's a new shell (in future) and a programming language focused on systems engineering tasks. The next milestones are documentation and packaging. The documentation is almost ready. I would like to get some feedback on the language introduction documentation: comments here, github issues, and pull requests with fixes are all welcome.
