-This is a implementation for the PSR-6 for a filesystem cache. This implementation supports tags. This adapter 
-requires [Flysystem](http://flysystem.thephpleague.com/).
+This is a PSR-6 cache implementation for Filesystem. 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). 
 
-| Feature | Supported |
-| ------- | --------- | 
-| Flush everything | Yes 
-| Expiration time | Yes
-| Support for tags | Yes
+This implementation is using the excellent [Flysystem](http://flysystem.thephpleague.com/).
+
+### Install
+
+```bash
+composer require cache/filesystem-adapter
+```
+
+### Configure
+
+To create an instance of `FilesystemCachePool` you need to configure a `Filesystem` and its adapter. 
+
+```php
+use League\Flysystem\Adapter\Local;
+use League\Flysystem\Filesystem;
+use Cache\Adapter\Filesystem\FilesystemCachePool;
+
+$filesystemAdapter = new Local(__DIR__.'/');
+$filesystem        = new Filesystem($filesystemAdapter);
+
+$pool = new FilesystemCachePool($filesystem);
+```
