 Websockets
 =================
 
-`websockets` are a great way to add a two way instant data channel between server and client. This example was taken from the `copilot` extension, we create a websocket endpoint which can be restricted by `id`, then can feed it data to broadcast to any client on the socket using the `updater(extension_id, data)` function (`extension` has been used in place of an extension name, wreplace to your own extension):
+`websockets` are a great way to add a two way instant data channel between server and client. 
 
+LNbits has a useful in built websocket tool. With a websocket client connect to (obv change `somespecificid`) `wss://legend.lnbits.com/api/v1/ws/somespecificid` (you can use an online websocket tester). Now make a get to `https://legend.lnbits.com/api/v1/ws/somespecificid/somedata`. You can send data to that websocket by using `from lnbits.core.services import websocketUpdater` and the function `websocketUpdater("somespecificid", "somdata")`.

+          Before you continue to the wallet, make sure to open this page in your
+          device's native browser application (Safari for iOS, Chrome for
+          Android). Do not use Cashu in an embedded browser that opens when you

+          You can add Cashu to your home screen as a progressive web app (PWA).
+          After opening the wallet in your browser (click the link above), on
+          Android (Chrome), click the menu at the upper right. On iOS (Safari),
+          click the share button. Now press the Add to Home screen button.

+          Ecash is a bearer asset. That means losing access to your wallet will
+          make you lose your funds. The wallet stores ecash tokens on your
+          device's database. If you lose the link or delete your your data
+          without backing up, you will lose your tokens. Press the Backup button
+          in the wallet to download a copy of your tokens.

 When scanned, the QR code sends up information about the song playing at the moment (name and the producer of that song). Also, if the user likes the song and would like to support the producer, he can send a tip and a message for that specific track. If the user sends an amount over a specific threshold they will be given a link to download it (optional).
