This site should really have some code examples on the main pages. I shouldn't have to watch videos to get a basic idea of the syntax and what it can do. The blog on the front has some code, but it's not geared towards explaining the basic ideas.
About the syntax and semantics, in a nutshell, it's a Lisp without parentheses and with infix operator support. Tokens are separated by a whitespace or a delimiter (very few of them). Code is a tree of lists (called "blocks" in our local jargon), blocks are delimited by square brackets [].
You can have a look here [1] for a larger code and syntax example.
