+/**
+ * Configurable is the interface that should be implemented by classes who support configuring
+ * its properties through the last parameter to its constructor.
+ *
+ * The interface does not declare any method. Classes implementing this interface must declare their constructors
+ * like the following:
+ *
+ * ```php
+ * public function __constructor($param1, $param2, ..., $config = [])
+ * ```
+ *
+ * That is, the last parameter of the constructor must accept a configuration array.
+ *
+ * This interface is mainly used by [[\yii\di\Container]] so that it can pass object configuration as the
+ * last parameter to the implementing class' constructor.
+ *
+ * For more details and usage information on Configurable, see the [guide article on configurations](guide:concept-configurations).
