+Django components
+=================
+
+``swh-auth`` implements some generic backends, models, views and middlewares
+to easily authenticate a user with Keycloak and OpenID Connect.
+
+
+OIDC User model
+---------------
+
+When ``swh-auth`` authenticates users with OIDC in a Django application,
+it creates an instance of the :class:`swh.auth.django.models.OIDCUser`
+model and attaches it to the input ``django.http.HttpRequest`` object.
+
+That model acts as a proxy for the ``django.contrib.auth.models.User`` model
+and is not persisted to database as user information is already stored
+in Keycloak database. As a consequence it will not be considered when calling
+the ``makemigrations`` command from Django application management CLI.
+
+
+Authentication backends
+-----------------------
+
+``swh-auth`` provides two authentication backends to login users in
+Django applications:
+
+- :class:`swh.auth.django.backends.OIDCAuthorizationCodePKCEBackend`: authenticate
+  users from a Web application UI
+
+- :class:`swh.auth.django.backends.OIDCBearerTokenAuthentication`: authenticate
+  REST API users from bearer tokens sent in HTTP Authorization headers.
+
+These backends need to be configured through the following Django settings:
+
+- ``SWH_AUTH_SERVER_URL``: Base URL of the Keycloak server to interact with
+
+- ``SWH_AUTH_REALM_NAME``: Name of the realm to use in the Keycloak instance
+
+- ``SWH_AUTH_CLIENT_ID``: Name of the client to use in the realm
+
+.. warning::
+
+  These backends internally use the Django cache to store authenticated user data.
+  In production environment, it is important to ensure the cache will be shared
+  across the multiple WSGI workers (by using Django memcached cache backend
+  for instance).
+
+Authorization Code flow with PKCE backend
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+This backend can be used to authenticate users with the OpenID Connect Authorization
+Code flow with PKCE (`Proof Key for Code Exchange`_).
+
+PKCE replaces the static secret used in the standard authorization code flow with a
+temporary one-time challenge, making it feasible to use in public clients.
+
+When using that backend, users are redirected to the Keycloak login UI and are
+asked to enter their credentials. Once successfully authenticated, users will
+be redirected back to the Django application.
+
+To use that backend, add ``"swh.auth.django.backends.OIDCAuthorizationCodePKCEBackend"``
+to the ``AUTHENTICATION_BACKENDS`` Django setting.
+
+The backend must be used in collaboration with the dedicated :ref:`login-logout-views`
+implementing the authentication flow.
+
+Bearer token backend
+^^^^^^^^^^^^^^^^^^^^
+
+This backend for Django REST Framework enables to authenticate Web API users by sending
+long-lived OpenID Connect refresh tokens in HTTP Authorization headers.
+
+Long lived refresh tokens can be generated in Keycloak by opening an OpenID Connect
+session with the following scope: ``openid offline_access``.
+
+To use that backend, add ``"swh.auth.django.backends.OIDCBearerTokenAuthentication"``
+to the ``REST_FRAMEWORK["DEFAULT_AUTHENTICATION_CLASSES"]`` Django setting.
+
+Users can then perform authenticated Web API calls by sending their refresh token
+in HTTP Authorization headers, for instance when using ``curl``::
+
+  curl -H "Authorization: Bearer ${TOKEN}" https://....
+
+.. _login-logout-views:
+
+Login / logout views
+--------------------
+
+In order to login / logout a user with OIDC Authorization code flow with PKCE, two
+dedicated Django views are available in ``swh-auth``:
+
+- ``oidc-login`` (``/oidc/login/`` URL path): initiate authentication flow
+
+- ``oidc-logout`` (``/oidc/logout/`` URL path): terminate OIDC user session, a ``next_path``
+  query parameter can be used to redirect to a view of choice once a user is logged out
+
+Add ``swh.auth.django.views.urlpatterns`` to your Django application URLs to use them.
+
+Middlewares
+-----------
+
+``swh-auth`` provides the :class:`swh.auth.django.middlewares.OIDCSessionExpiredMiddleware`
+middleware.
+
+That middleware detects when a user previously logged in using the OpenID Connect
+authentication backend got his session expired.
+
+In that case it redirects to a Django view whose name is set in the
+``SWH_AUTH_SESSION_EXPIRED_REDIRECT_VIEW`` Django setting (typically a logout view).
+
+The following query parameter will be set for that view:
+
+- ``next_path``: requested URL before the detection of the OIDC session expiration
+
+- ``remote_user``: indicates that the user was previously authenticated with OIDC
+
+Minimal application example
+---------------------------
+
+A sample minimal Django application using all the features mentioned above can be
+found in `swh-auth Django tests tree`_.
