+## Features
+
+- Similar user experience as the official client in macOS.
+- Supports both SAML and non-SAML authentication modes.
+- Supports automatically selecting the preferred gateway from the multiple gateways.
+- Supports switching gateway from the system tray menu manually.
 
-- Openconnect v8.x
-- Qt5, qt5-webengine, qt5-websockets
 
-### Ubuntu
-1. Install openconnect v8.x
-    Update openconnect to 8.x, for ubuntu 18.04 you might need to [build the latest openconnect from source code](https://gist.github.com/yuezk/ab9a4b87a9fa0182bdb2df41fab5f613).
-2. Install the Qt dependencies
-    ```sh
-    sudo apt install qt5-default libqt5websockets5-dev qtwebengine5-dev
-    ```
