 This class is a basic implementation of a Container. It is inspired by PSR-11 Container Interface but with stripped down with a bare minimum feature for maximum compatibility within the WordPress ecosystem!
 
-This Container contains only one class than can easily be copied, modified, and adjusted to your needs.
+This Container contains only one class than can easily be copied, modified, and adjusted to your needs. This class is designed to be a drop-in class for any plugin or theme.
 
 Supports PHP 5.6 or above and Autowiring.
 
+
+
+
+## Installation
+- Rename the class by modifying the namespace and/or the class name.
+- Use it! See usage below.
 ## Usage
 
 ```php
     // Require the Container class file.
     require_once __DIR__ . '/class-container.php';
 
-    // Instantiate.
-    $container = new Container();
+    // Instantiate. Replace the class name with your own.
+    $container = new DIC\WP\Container();
 ```
 
+## Example Usage
+
+Without this class we would have to wire our dependencies like the following:
+
+```php
+// Say we have 4 classes, 
+// Foo which has Bar and Zag dependencies,
+// Bar with Zig dependency,
+// Zig, and Zag without any dependencies.
+
+class Foo {
+    protected $bar;
+    protected $zag;
+    public function __construct( Bar $bar, Zag $zag ) {
+        $this->bar = $bar;
+        $this->zag = $zag;
+    }
+}
+
+class Bar {
+    protected $zig;
+    public function __construct( Zig $zig ) {
+        $this->zig = $zig;
+    }
+}
+
+class Zig {
+    // ...
+}
+
+class Zag {
+    // ...
+}
+
+$foo = new Foo( new Bar( new Baz() ), new Zag() );
+```
