Precise defitition of the peg syntax?

[winny-]

What's the easiest way to understand the peg syntax? I saw https://docs.racket-lang.org/peg/index.html#%28part..P.E.G.Syntax_.Reference%29 . Is there some additional reference material one should review? Thx

Not quite sure on the syntax for the peg language (such as which syntax sugar translates to a peg racket form). I mainly copy-pasted examples and tweaked them until they stopped failing to compile
