-- `Container` - provides immutable properties with magic getter & setter and some fancy, implements `ContainerInterface`
+- `ImmutableSettingsContainer` - provides immutable properties with magic getter & setter and some fancy, implements `ImmutableSettingsInterface`
 - `Magic` - turns methods into magic properties
 - `Enumerable` - provides some of [prototype's enumerable methods](http://api.prototypejs.org/language/Enumerable/), implements `EnumerableInterface`
 - `Env` - loads contents from a `.env` file into the environment (similar to [vlucas/phpdotenv](https://github.com/vlucas/phpdotenv))

-#### `Container`
+#### `ImmutableSettingsContainer`
+
+The `ImmutableSettingsContainer` trait (wrapped in`ImmutableSettingsAbstract` ) provides plug-in functionality for immutable object variables and adds some fancy, like loading/saving JSON, arrays etc. 
+It takes an array (planned: iterable) as the only constructor argument and calls a method (`MyTrait::MyTrait()`) for each trait on invocation.
+
+##### Simple usage
 ```php
-class MyContainer implements ContainerInterface{
-	use Container;
+class MyContainer extends ImmutableSettingsAbstract{
 
 	protected $foo;
 	protected $bar;
+
 }
 ```

 #### `Magic`
 `Magic` allows to access internal methods like as properties.
