+=======================
+ Limit number of users
+=======================
+
+With this module you can limit number of users.
+
+This module creates record with external id `access_limit_max_users.max_users_limit`
+that defines max amount of users can have current database. By default it is
+number of active users at moment of installation of this module.
+
+In order to make user to be ignoring the limit, you can use field ``is_excluded_from_limiting`` in one of the following ways:
+
+* Create or set ``is_excluded_from_limiting`` to True in supersuper (sudo) mode. See `<tests/test_excluded_users.py>`_
+* Define user record in `data files <https://www.odoo.com/documentation/14.0/reference/data.html>`__ with ``is_excluded_from_limiting`` set to True.
