Issues because of Catalog renamed to Tree

[marc2332]

Hello,

I am trying to follow this tutorial, but, I am unable to do because it's a bit outdated. It explains the old Catalog, now renamed to Tree (source), and because of expecting from_catalog instead of from_tree, it gives some errors.

Here, it tries to import from_catalog:

Is there any plan to update the tutorials?

Thanks! :D
