 Installing Symfony
 ------------------
 
-There is only one recommended way to install Symfony:
+In the past, Symfony projects were created with `Composer`_, the dependency manager
+for PHP applications. However, the current recommendation is to use the **Symfony
+Installer**, which has to be installed before creating your first project.
 
-.. best-practice::
-
-    Always use `Composer`_ to install Symfony.

-Composer is the dependency manager used by modern PHP applications. Adding or
-removing requirements for your project and updating the third-party libraries
-used by your code is a breeze thanks to Composer.

-Dependency Management with Composer

+Linux and Mac OS X Systems
+~~~~~~~~~~~~~~~~~~~~~~~~~~
 
-Before installing Symfony, you need to make sure that you have Composer installed
-globally. Open your terminal (also called *command console*) and run the following
-command:
+Open your command console and execute the following:
 
 .. code-block:: bash
 
-    $ composer --version

+    $ sudo mv symfony.phar /usr/local/bin/symfony
+    $ chmod a+x /usr/local/bin/symfony
 
-You'll probably see a different version identifier. Never mind because Composer
-is updated on a continuous basis and its specific version doesn't matter.
+Now you can execute the Symfony Installer as a global system command called
+``symfony``.
 
-Installing Composer Globally
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+Windows Systems
+~~~~~~~~~~~~~~~
 
-In case you don't have Composer installed globally, execute the following two
-commands if you use Linux or Mac OS X (the second command will ask for your
-user password):
+Open your command console and execute the following:
 
 .. code-block:: bash
 
-    $ curl -sS https://getcomposer.org/installer | php
-    $ sudo mv composer.phar /usr/local/bin/composer
+    c:\> php -r "readfile('http://symfony.com/installer');" > symfony.phar
 
-.. note::
+Then, move the downloaded ``symfony.phar`` file to your projects directory and
+execute it as follows:
 
-    Depending on your Linux distribution, you may need to execute ``su`` command
-    instead of ``sudo``.
+.. code-block:: bash
 
-If you use a Windows system, download the executable installer from the
-`Composer download page`_ and follow the steps to install it.
