Adding a Plone addon to the backend in backend/requirements.txt is not taken by git.

When you need to add an Plone addon to the backend and you follow the instructions on page /admin-guide/add-ons.html you would add the package to the file backend/requirements.txt, the change does not show up in git.

see: https://6.docs.plone.org/admin-guide/add-ons.html#install-an-add-on

Goal: Explain the right place to add the addons in the docs matching the Cookiecutter setup (or the other way round)

• The docs should refer to the right place to add the addons and constraints in a Cookiecutter based setup!
• or the Cookiecutter based setup needs to match the docs!
• Optional: Add a reference to the related latest docs in the main README.md or backend/README.md

Solution?

I cannot suggest a PR because I am not aware of the latest changes and where the issue has to be fixed

backend/requirements.txt is covered in the backend/.gitignore rules

Version from the README.md:
Generated using Cookieplone (0.9.6) and cookieplone-templates (696f111) on 2025-04-10 15:15:45.110547.

In this setup in the backend/.gitignore contains:

...
# mxdev
...
/*-mxdev.txt
...
constraints*.txt
requirements*.txt

Other stuff

There is no setup.py anymore
