 If you want you can use sequence plugin that generates next value based on sequence space.
 Or you can implement id generator using any other source, for example with raft protocol.
 ```php
-$pattern = $mapper->getSchema()->createSpace('shift_pattern');
-$pattern->addProperty('id', 'unsigned');
-$pattern->addProperty('title', 'str');
-$pattern->addProperty('pattern', '*');
-$pattern->addIndex('id');
+$post = $mapper->getSchema()->createSpace('post');
+$post->addProperty('id', 'unsigned');
+$post->addProperty('title', 'str');
+$post->addProperty('body', 'str');
+$post->addIndex('id');
 
 $mappr->addPlugin(Tarantool\Mapper\Plugins\Sequence::class);
 
-$pattern = $mapper->create('shift_pattern', [
-  'title' => '5 days week',
-  'pattern' => [
-    ['work' => true],
-    ['work' => true],
-    ['work' => true],
-    ['work' => true],
-    ['work' => true],
-    ['work' => false],
-    ['work' => false],
-  ]
+$entity = $mapper->create('post', [
+  'title' => 'Autoincrement implemented',
+  'body' => 'You can use Sequence plugin to track and fill your entity id'
 ]);
 
-echo $pattern->id; // will be set when you create an instance
+echo $entity->id; // will be set when you create an instance
 ```
