Description

Currently no example is being shown of a URL redirect which has multiple targets.

I'm currently running into a problem for ex where I can't get a working url redirect working (although mine is more complicated the example i'm asking for is probably):

^https://(medium.com|betterhumans.coach.me|ai.plainenglish.io|drlee.io)(/.*)?|https://scribe.pussthecat.org$2

Also the docs are directing users to regex101 and such. But don't even pass the simple examples given (the / isn't escaped, it complains).

I have little regex experience, so maybe it's just me. But yeah, this is confusing and could be improved

again, linking to regex101 is bad cause it will never validate correctly.

While this isn't a website for validating, it does help with visualizting, so it's worth adding atleast this: regex-viz

example
