+
+## Features
+
+PhpDocReader parses `@var` and `@param` values in PHP docblocks:
+
+```php
+
+use My\Cache\Backend;
+
+class Cache
+{
+    /**
+     * @var Backend
+     */
+    protected $backend;
+
+    /**
+     * @param Backend $backend
+     */
+    public function __construct($backend)
+    {
+    }
+}
+```
+
+It supports namespaced class names with the same resolution rules as PHP:
+
+- fully qualified name (starting with `\`)
+- imported class name (eg. `use My\Cache\Backend;`)
+- relative class name (from the current namespace, like `SubNamespace\MyClass`)
+- aliased class name  (eg. `use My\Cache\Backend as FooBar;`)
+
+Primitive types (`@var string`) are ignored (returns null), only valid class names are returned.
+
+## Usage
+
+```php
+$reader = new PhpDocReader();
+
+// Read a property type (@var phpdoc)
+$property = new ReflectionProperty($className, $propertyName);
+$propertyClass = $reader->getPropertyClass($property);
+
+// Read a parameter type (@param phpdoc)
+$parameter = new ReflectionParameter(array($className, $methodName), $parameterName);
+$parameterClass = $reader->getParameterClass($parameter);
+```
