What is the breathe path?

Question

The following steps are required to integrate breathe functionality:

1. Add the breathe path to your conf.py by adding the following line:

sys.path.append("/home/me/docproj/ext/breathe/")

_{https://breathe.readthedocs.io/en/latest/quickstart.html}

What is this breathe path and how do I find it on my system?

I installed breathe as a Python package, i.e. with pip3 install breathe, so is that supposed to be the Python package "Location" value, as reported by pip3 show, e.g.:

$ pip3 show breathe
Name: breathe
Version: 4.35.0
Summary: Sphinx Doxygen renderer

?

There's no breathe executable:

$ which breathe
$   

That example value in the quickstart guide doesn't at all look like the Python dist-packages/ directory, and I wasn't able to find anything that explained it at https://breathe.readthedocs.io/.
