 Debug Component
 ===============
 
-The Debug component provides tools to ease debugging PHP code.
+Debug provides tools to make debugging easier.
+
+Enabling all debug tools is as easy as calling the `enable()` method on the
+main `Debug` class:
+
+```php
+use Symfony\Component\Debug\Debug;
+
+Debug::enable();
+```
+
+You can also use the tools individually:
+
+```php
+use Symfony\Component\Debug\DebugClassLoader;
+use Symfony\Component\Debug\ErrorHandler;
+use Symfony\Component\Debug\ExceptionHandler;
+
+if ('cli' !== php_sapi_name()) {
+    ini_set('display_errors', 0);
+    ExceptionHandler::register();
+} elseif (!ini_get('log_errors') || ini_get('error_log')) {
+    ini_set('display_errors', 1);
+}
+ErrorHandler::register();
+DebugClassLoader::enable();
+```
+
+This component can optionally take advantage of the features of the HttpKernel
+component.
