+
+Abstract example:
+
+```php
+use Dflydev\DotAccessData\Data;
+
+$data = new Data;
+
+$data->set('a.b.c', 'C');
+$data->set('a.b.d', 'D1');
+$data->append('a.b.d', 'D2');
+$data->set('a.b.e', array('E0', 'E1', 'E2'));
+
+// C
+$data->get('a.b.c');
+
+// array('D1', 'D2')
+$data->get('a.b.d');
+
+// array('E0', 'E1', 'E2')
+$data->get('a.b.e');
+
+// true
+$data->has('a.b.c');
+
+// false
+$data->has('a.b.d.j');
+```
+
+A more concrete example:
+
+```php
+use Dflydev\DotAccessData\Data;
+
+$data = new Data(array(
+    'hosts' => array(
+        'hewey' => array(
+            'username' => 'hman',
+            'password' => 'HPASS',
+            'roles' => array('web'),
+        ),
+        'dewey' => array(
+            'username' => 'dman',
+            'password' => 'D---S',
+            'roles' => array('web', 'db'),
+            'nick' => 'dewey dman'
+        ),
+        'lewey' => array(
+            'username' => 'lman',
+            'password' => 'LP@$$',
+            'roles' => array('db'),
+        ),
+    )
+));
+
+// hman
+$username = $data->get('hosts.hewey.username');
+// HPASS
+$password = $data->get('hosts.hewey.password');
+// array('web')
+$roles = $data->get('hosts.hewey.roles');
+// dewey dman
+$nick = $data->get('hosts.dewey.nick');
+// Unknown
+$nick = $data->get('hosts.lewey.nick', 'Unknown');
+
+// DataInterface instance
+$dewey = $data->getData('hosts.dewey');
+// dman
+$username = $dewey->get('username');
+// D---S
+$password = $dewey->get('password');
+// array('web', 'db')
+$roles = $dewey->get('roles');
+
+// No more lewey
+$data->remove('hosts.lewey');
+
+// Add DB to hewey's roles
+$data->append('hosts.hewey.roles', 'db');
+
+$data->set('hosts.april', array(
+    'username' => 'aman',
+    'password' => '@---S',
+    'roles' => array('web'),
+));
+
+// Check if a key exists (true to this case)
+$hasKey = $data->has('hosts.dewey.username');
