An addon module is a directory containing files that implement some Odoo features. It can add new features or modify existing ones. The addon module directory must contain a manifest file—or descriptor file—named __manifest__.py.

Some module addons are featured as an app. Apps are the top-level module for a feature area in Odoo, and we expect our module to be featured in the top-level Apps menu.

2. Create the module's directory, containing the...
