+# Mount Manager
+
+Flysystem comes with an wrapper class to easily work with multiple file system instances
+from a single object. The `League\Flysystem\MountManager` is an easy to use container allowing
+you to simplify more complex cross file system interactions.
+
+Setting up a Mount Manager is easy:
+
+~~~ php
+$ftp = new League\Flysystem\Filesystem($ftpAdapter);
+$s3 = new League\Flysystem\Filesystem($s3Adapter);
+$local = new League\Flysystem\Filesystem($localAdapter);
+
+// Add them in the constructor
+$manager = new League\Flysystem\MountManager([
+    'ftp' => $ftp,
+    's3' => $s3,
+]);
+
+// Or mount them later
+$manager->mountFilesystem('local', $local);
+~~~
+
+Now we do all the file operations we'd normally do on a `Flysystem\Filesystem` instance.
+
+~~~ php
+// Read from FTP
+$contents = $manager->read('ftp://some/file.txt');
+
+// And write to local
+$manager->write('local://put/it/here.txt', $contents);
+~~~
+
+This makes it easy to code up simple sync strategies.
+
+~~~ php
+$contents = $manager->listContents('local://uploads', true);
+
+foreach ($contents as $entry) {
+    $update = false;
+
+    if ( ! $manager->has('storage://'.$entry['path'])) {
+        $update = true;
+    } elseif ($manager->getTimestamp('local://'.$entry['path']) > $manager->getTimestamp('storage://'.$entry['path'])) {
+        $update = true;
+    }
+
+    if ($update) {
+        $manager->put('storage://'.$entry['path'], $manager->read('local://'.$entry['path']));
+    }
+}
+~~~
+
+## Specialized calls
+
+### Copy
+
+The copy method provided by the Mount Manager takes the origin of the file into account.
+When it detects the source and destination are located on a different file systems it'll
+use a streamed upload instead, transparently.
+
+~~~ php
+$mountManager->copy('local://some/file.ext', 'backup://storage/location.ext');
+~~~
+
+### Move
+
+The `move` call is the multi-file system counterpart to `rename`. Where rename must be used on
+the same file system, the `move` call provides the same conceptual behavior, but then on two
+different file systems.
+
+~~~ php
+$mountManager->move('local://some/upload.jpeg', 'cdn://users/1/profile-picture.jpeg');
+~~~
