 This is a implementation for the PSR-6 for an hierarchical cache architecture. 
 
 If you have a cache key like `|users|:uid|followers|:fid|likes` where `:uid` and `:fid` are arbitrary integers. You
  may flush all followers by flushing `|users|:uid|followers`.
+  
+It is a part of the PHP Cache organisation. To read about features like tagging and hierarchy support please read 
+the shared documentation at [www.php-cache.com](http://www.php-cache.com). 
+
+### Install
+
+```bash
+composer require cache/hierarchical-cache
+```
 
-```php
-$user = 4711;
-for ($i = 0; $i < 100; $i++) {
-  $item = $pool->getItem(sprintf('|users|%d|followers|%d|likes', $user, $i));
-  $item->set('Justin Bieber');
-  $pool->save($item);
-}
+### Use
 
-$pool->hasItem('|users|4711|followers|12|likes'); // True
+Read the [documentation on usage](http://www.php-cache.com/en/latest/hierarchy/).
