How to open a bloom pack?

I was sent a bloom pack, but I can’t get it to open in Bloom…
I unzipped the file and saved it in Document/Bloom/Book folder… Then tried to open it from Bloom through Other Collection… but the file is not openable this way.

Double-clicking a .bloompack file will install the templates on your machine and make them available in your “sources for new shells” in the next time you open Bloom.
