+SensioLabs Security Checker
+===========================
+
+The SensioLabs Security Checker is a command line tool that checks if your
+application uses dependencies with known security vulnerabilities. It uses the
+[Security Check Web service][1] and the [Security Advisories Database][2].
+
+**TIP**: As an alternative, you can use the [Symfony CLI][3] tool that has the
+following advantages: it does not depend on PHP, all checks are done locally (no
+calls to the security.symfony.com API):
+
+    $ symfony security:check
+
+Usage
+-----
+
+Download the [security-checker.phar][4] file:
+
+    $ php security-checker.phar security:check /path/to/composer.lock
+
+Use the code from the repository directly:
+
+    $ composer install
+    $ php security-checker security:check /path/to/composer.lock
+
+Integration
+-----------
+
+The checker uses the Symfony Console component; so, you can easily integrate
+the checker into your own project:
+
+ * by using the `SecurityCheckerCommand` class into your Symfony Console
+   application;
+
+ * by using the `SecurityChecker` class directly into your own code:
+
+        use SensioLabs\Security\SecurityChecker;
+
+        $checker = new SecurityChecker();
+        $result = $checker->check('/path/to/composer.lock', 'json');
+        $alerts = json_decode((string) $result, true);
