Description

Reading the description of grouping and flags, I'm confused about how those flags would apply to theoretical strings. An example or two would be good to demonstrate the use and placement of flags, as well as the resulting capture groups.

Contributor guide

Research direction
Examine the existing regexp/syntax documentation and add clear examples demonstrating flag usage and capture groups.
