+# Plugins
+Need a feature which is not included in Flysystem's bag of tricks? Write a plugin!
+
+~~~ php
+use League\Flysystem\FilesystemInterface;
+use League\Flysystem\PluginInterface;
+
+class MaximusAwesomeness implements PluginInterface
+{
+    protected $filesystem;
+
+    public function setFilesystem(FilesystemInterface $filesystem)
+    {
+        $this->filesystem = $filesystem;
+    }
+
+    public function getMethod()
+    {
+        return 'getDown';
+    }
+
+    public function handle($path = null)
+    {
+        $contents = $this->filesystem->read($path);
+
+        return sha1($contents);
+    }
+}
+~~~
+
+Now we're ready to use the plugin
+
+~~~ php
+use League\Flysystem\Filesystem;
+use League\Flysystem\Adapter;
+
+$filesystem = new Filesystem(new Adapter\Local(__DIR__.'/path/to/files/'));
+$filesystem->addPlugin(new MaximusAwesomeness);
+$sha1 = $filesystem->getDown('path/to/file');
+~~~
