I'm trying to create my first module by following instructions from docs (https://www.odoo.com/documentation/8.0/howtos/backend.html#build-an-odoo-module), but it seems that the scaffolding command doesn't generate proper files.

It only generates 3 files : demo.xml, templates.xml and security/ir.model.access.csv. 

The generated module doesn't appear in local module screen.

I'm using the official docker image.
