I don't think it's a separate document.

What Beth wrote:

Instead of a 0 rating maybe have the heading read, Intro to Paddling.

A beginner paddle where you show new people a lot of the basics by example and have a nice time. It's that simple.
Or the picnic as it's written. Beth is just changing a 0 to "Intro". I think a lot of people find the 0 silly.
