+This repository hosts the code for the bases and solutions of the
+[official Odoo tutorials](https://www.odoo.com/documentation/17.0/developer/tutorials.html).
 
-It has 3 branches for each Odoo version: one for the bases, one for the
-[Discover the JS framework](https://www.odoo.com/documentation/latest/developer/tutorials/discover_js_framework.html)
-tutorial's solutions, and one for the
-[Master the Odoo web framework](https://www.odoo.com/documentation/latest/developer/tutorials/master_odoo_web_framework.html)
-tutorial's solutions. For example, `17.0`, `17.0-discover-js-framework-solutions` and
-`17.0-master-odoo-web-framework-solutions`.
