 ## Establishing a connection
 Start by connecting to the Flipper server running within the desktop app. Connecting to the server registers your application with Flipper and enables plugins to interact with it. As the Flipper desktop has a different lifecycle than your app and may connect and disconnect at any time it is important that you attempt to reconnect to the Flipper server until it accepts your connection.
