 Debug Component
 ===============
 
+**CAUTION**: this component is deprecated since Symfony 4.4. Instead, use the
+[ErrorHandler component](https://github.com/symfony/symfony/tree/master/src/Symfony/Component/ErrorHandler).
+
+-----
+
 The Debug component provides tools to ease debugging PHP code.
 
+Getting Started
+---------------
+
+```
+$ composer install symfony/debug
+```
+
+```php
+use Symfony\Component\Debug\Debug;
+
+Debug::enable();
+```
