# 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');
