+EmbyUpdate Plugin
+=================
+
+``embyupdate`` is a plugin that lets you automatically update `Emby`_'s library whenever you change your beets library.
+
+To use ``embyupdate`` plugin, enable it in your configuration (see :ref:`using-plugins`). Then, you'll probably want to configure the specifics of your Emby server. You can do that using an ``emby:`` section in your ``config.yaml``, which looks like this::
+
+    emby:
+        host: localhost
+        port: 8096
+        username: user
+        password: password
+
+To use the ``embyupdate`` plugin you need to install the `requests`_ library with::
+
+    pip install requests
+
+With that all in place, you'll see beets send the "update" command to your Emby server every time you change your beets library.
+
+.. _Emby: http://emby.media/
+.. _requests: http://docs.python-requests.org/en/latest/
+
+Configuration
+-------------
+
+The available options under the ``emby:`` section are:
+
+- **host**: The Emby server name.
+  Default: ``localhost``
+- **port**: The Emby server port.
+  Defailt: 8096
+- **username**: A username of a Emby user that is allowed to refresh the library.
+- **password**: That users password.
