+Articles behind a paywall
+=========================
+
+wallabag can fetch articles from websites which use a paywall system.
+
+Enable paywall authentication
+-----------------------------
+
+In internal settings, in the **Article** section, enable authentication for websites with paywall (with the value 1).
+
+Configure credentials in wallabag
+---------------------------------
+
+Edit your ``app/config/parameters.yml`` file to edit credentials for each website with paywall. Here is an example for some french websites:
+
+.. code:: yaml
+
+    sites_credentials:
+        mediapart.fr: {username: "myMediapartLogin", password: "mypassword"}
+        arretsurimages.net: {username: "myASILogin", password: "mypassword"}
+
+.. note::
+
+    These credentials will be shared between each user of your wallabag instance.
+
+Parsing configuration files
+---------------------------
+
+.. note::
+
+    Read `this part of the documentation <http://doc.wallabag.org/en/master/user/errors_during_fetching.html>`_ to understand the configuration files.
+
+Each parsing configuration file needs to be improved by adding ``requires_login``, ``login_uri``,
+``login_username_field``, ``login_password_field`` and ``not_logged_in_xpath``.
+
+Be careful, the login form must be in the page content when wallabag loads it. It's impossible for wallabag to be authenticated
+on a website where the login form is loaded after the page (by ajax for example).
+
+``login_uri`` is the action URL of the form (``action`` attribute in the form).
+``login_username_field`` is the ``name`` attribute of the login field.
+``login_password_field`` is the ``name`` attribute of the password field.
+
+For example:
+
+.. code::
+
+    title://div[@id="titrage-contenu"]/h1[@class="title"]
+    body: //div[@class="contenu-html"]/div[@class="page-pane"]
+
+    requires_login: yes
+
+    login_uri: http://www.arretsurimages.net/forum/login.php
+    login_username_field: username
+    login_password_field: password

+Articles derrière un paywall
+============================
+
+wallabag peut récupérer le contenu des articles des sites qui utilisent un système de paiement.
+
+Activer l'authentification pour les paywall
+-------------------------------------------
+
+Dans les paramètres internes, section **Article**, activez l'authentification pour les articles derrière un paywall (avec la valeur 1).
+
+Configurer les accès dans wallabag
+----------------------------------
+
+Éditez le fichier ``app/config/parameters.yml`` pour modifier les accès aux sites avec paywall. Voici un exemple pour certains sites :
+
+.. code:: yaml
+
+    sites_credentials:
+        mediapart.fr: {username: "myMediapartLogin", password: "mypassword"}
+        arretsurimages.net: {username: "myASILogin", password: "mypassword"}
+
+.. note::
+
+    Ces accès seront partagés entre chaque utilisateur de votre instance wallabag.
+
+Fichiers de configuration pour parser les articles
+--------------------------------------------------
+
+.. note::
+
+    Lisez `cette documentation <http://doc.wallabag.org/fr/master/user/errors_during_fetching.html>`_ pour en savoir plus sur ces fichiers de configuration.
+
+Chaque fichier de configuration doit être enrichi en ajoutant ``requires_login``, ``login_uri``,
+``login_username_field``, ``login_password_field`` et ``not_logged_in_xpath``.
+
+Attention, le formulaire de connexion doit se trouver dans le contenu de la page lors du chargement de celle-ci.
+Il sera impossible pour wallabag de se connecter à un site dont le formulaire de connexion est chargé après coup (en ajax par exemple).
+
+``login_uri`` correspond à l'URL à laquelle le formulaire est soumis (attribut ``action`` du formulaire).
+``login_username_field`` correspond à l'attribut ``name`` du champ de l'identifiant.
+``login_password_field`` correspond à l'attribut ``name`` du champ du mot de passe.
+
+Par exemple :
+
+.. code::
+
+    title://div[@id="titrage-contenu"]/h1[@class="title"]
+    body: //div[@class="contenu-html"]/div[@class="page-pane"]
+
+    requires_login: yes
+
+    login_uri: http://www.arretsurimages.net/forum/login.php
+    login_username_field: username
+    login_password_field: password
