      I'm trying to follow this tutorial https://frappe.io/tutorial/doctype-directory-structure everything went almost smoothly, but I don't have the doctype directory structure. Is it normal?

[frappe@localhost library_management]$ tree

All my doctypes are saved without errors, and custom is checked as shown in the tutorial.
