 I suggest you have pipenv installed, this projet is writtent under python 3.12 and may work on other versiona
 We have a requirement of being virtualenv compatible while i will  working with Pipenv.

+Testing
+-------
+
+Unitest should run flawlessly using make test, however functionnal testing may require some extra work.
+
+Functional testing requires *geckodriver* and *selenium* which is a driver to programatically control firefox (so one ca reproduce user behavior)
