I've forgotten how to allow a person to view one of my trees on Ancestry

[ThrelfallYorky]

Having thought that I could do it, I created a very simplified tree of one line of my ancestry that someone I know is interested in, and that we both share. She is an Ancestry member, too.
I have been given access to other people's trees in the past, and I allowed someone access to my main tree, I think - but I can't remember how to do it - and is it possible to manage to give access to it for only that one tree, not any others one has on Ancestry? I can't actually seem to come upon any help from Ancestry itself.
Guidance / advice would be most welcome. I'm feeling dim about it.

Click on TREES and then at the bottom CREATE and MANAGE TREES

move your cursor to the tree you want to share and click on TREE SETTINGS at far right of it.

Then at the top of the next page, under the TREE SETTINGS heading, click on SHARING
and then on the plus sign at the far right under INVITE PEOPLE.

This will give you various options of how to share.

And when you click on those, you can choose if you want them to be able to view or edit or contribute and see/not see living people (if appropriate).

Hope that helps!!

don't feel bad, I had to do it all myself to remember how it went

Thank you very much, your instructions sound most clear. I specifically only wanted to allow access to that one tree, and just for the person to see it. You are brilliant.
