-To create your new Symfony application, first make sure you're using PHP 7.1 or
-higher and have `Composer`_ installed. If you don't, start by `installing Composer`_.
+Installing Symfony
+------------------
 
-Create your new project by running:
+Before creating your first Symfony application, make sure to meet the following
+requirements:
+
+* Your server has PHP 7.1 or higher installed (and :doc:`these PHP extensions </reference/requirements>`
+  which are installed and enabled by default by PHP);
+* You have `installed Composer`_, which is used to install PHP packages;
+* You have installed the :doc:`Symfony local web server </setup/symfony_server>`,
+  which provides all the tools you need to develop your application locally.
+
+Once these requirements are installed, open your terminal and run any of these
+commands to create the Symfony application:
 
 .. code-block:: terminal
 
-    $ composer create-project symfony/website-skeleton my-project
+    # run this if you are building a traditional web application
+    $ symfony new --full my_project
 
-This will create a new ``my-project`` directory, download some dependencies into
-it and even generate the basic directories and files you'll need to get started.
-In other words, your new app is ready!
+    # run this if you are building a microservice, console application or API
+    $ symfony new my-project
 
-.. tip::
+The only difference between these two commands is the number of packages
+installed. The ``--full`` option installs all the packages that you usually
+need to build web apps. Therefore, the installation size will be much bigger.
 
-    The ``website-skeleton`` is optimized for traditional web applications. If
-    you are building microservices, console applications or APIs, consider
-    using the much simpler ``skeleton`` project:

-        $ composer create-project symfony/skeleton my-project
+    If you can't use the ``symfony`` command provided by the Symfony local web
+    server, use the alternative installation commands based on Composer and
+    displayed on the `Symfony download page`_.
 
 Running your Symfony Application

 On production, you should use a web server like Nginx or Apache (see
 :doc:`configuring a web server to run Symfony </setup/web_server_configuration>`).
 But for development, it's more convenient to use the

 How to Use PHP's built-in Web Server
 ====================================

 The PHP CLI SAPI comes with a `built-in web server`_. It can be used to run your
 PHP applications locally during development, for testing or for application
 demonstrations. This way, you don't have to bother configuring a full-featured
 web server such as :doc:`Apache or Nginx </setup/web_server_configuration>`.

+Run the following command to check whether your project's dependencies contain
+any known security vulnerability:
 
 .. code-block:: terminal
 
     $ symfony security:check
 
-This command uses the same vulnerability database as the Symfony Security
-Checker but it does not make HTTP calls to the official API endpoint. Everything
-(except cloning the public database) is done locally, which is the best for CI
-(*continuous integration*) scenarios.
+A good security practice is to execute this command regularly to be able to
+update or replace compromised dependencies as soon as possible. The security
+check is done locally by cloning the public `PHP security advisories database`_,
+so your ``composer.lock`` file is not sent on the network.
+
+.. tip::
+
+    The ``security:check`` command terminates with a non-zero exit code if
+    any of your dependencies is affected by a known security vulnerability.
+    This way you can add it to your project build process and your continuous
+    integration workflows to make them fail when there are vulnerabilities.
