+Symfony Demo Application
+========================
+
+The "Symfony Demo Application" is a reference application created to show how
+to develop applications following the [Symfony Best Practices][1].
+
+Requirements
+------------
+
+  * PHP 7.2.9 or higher;
+  * PDO-SQLite PHP extension enabled;
+  * and the [usual Symfony application requirements][2].
+
+Installation
+------------
+
+[Download Symfony][4] to install the `symfony` binary on your computer and run
+this command:
+
+```bash
+$ symfony new --demo my_project
+```
+
+Alternatively, you can use Composer:
+
+```bash
+$ composer create-project symfony/symfony-demo my_project
+```
+
+Usage
+-----
+
+There's no need to configure anything to run the application. If you have
+[installed Symfony][4] binary, run this command:
+
+```bash
+$ cd my_project/
+$ symfony serve
+```
+
+Then access the application in your browser at the given URL (<https://localhost:8000> by default).
+
+If you don't have the Symfony binary installed, run `php -S localhost:8000 -t public/`
+to use the built-in PHP web server or [configure a web server][3] like Nginx or
+Apache to run the application.
+
+Tests
+-----
+
+Execute this command to run tests:
+
+```bash
+$ cd my_project/
+$ ./bin/phpunit
+```
