+Migration guide
+===============
+
+This version incompatible with official extension due pk storage algorithm.
+To migrate to our version you should migrate your pks. Example code:
 
+```php
+function fill($keys)
+{
+    foreach ($keys as $key) {
+        yield $key;
+        yield 0;
+    }
+}
+
+$keys = $redis->executeCommand('LRANGE', ['model', 0, -1]);
+$keys = iterator_to_array(fill($keys));
+$keys = array_unshift($keys, 'model')
+
+$redis->executeCommand('DEL', 'model')
+$redis->executeCommand('HMSET', $keys)
+```
