     To define parameters with environment variables, you have to set these variables with ``SYMFONY__`` prefix. For example, ``SYMFONY__DATABASE_DRIVER``. You can have a look to the `Symfony documentation <http://symfony.com/doc/current/cookbook/configuration/external_parameters.html>`__.
 
-Installing on Apache

-Assuming you install wallabag in the /var/www/wallabag folder and that you want to use php as an Apache module, here's a vhost for wallabag:
+We provide you a package with all dependancies inside.
+The default configuration uses SQLite for the database. If you want to change these settings, please edit ``app/config/parameters.yml``.
+
+We already created a user: login and password are ``wallabag``.
+
+.. caution:: With this package, wallabag don't check mandatory extensions used in the application (theses checks are made during ``composer install`` when you have a dedicated web server, see above).
+
+Execute this command to download and extract the latest package:
+
+.. code-block:: bash
+
+    wget http://wllbg.org/latest-v2-package && tar xvf latest-v2-package
+
+Now, read the following documentation to create your virtual host, then access to your wallabag.
+If you changed the database configuration to use MySQL or PostgreSQL, you need to create a user via this command ``php bin/console wallabag:install --env=prod``.
