+Websockets
+=================
+
+`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")`.
+
+
+Example vue-js function for listening to the websocket:
+
+```
+initWs: async function () {
+    if (location.protocol !== 'http:') {
+        localUrl =
+          'wss://' +
+          document.domain +
+          ':' +
+          location.port +
+          '/api/v1/ws/' +
+          self.item.id
+      } else {
+        localUrl =
+          'ws://' +
+          document.domain +
+          ':' +
+          location.port +
+          '/api/v1/ws/' +
+          self.item.id
+      }
+    this.ws = new WebSocket(localUrl)
+    this.ws.addEventListener('message', async ({data}) => {
+      const res = JSON.parse(data.toString())
+      console.log(res)
+    })

+          Before you continue to the wallet, make sure to open this page in your

+          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.

+          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.

+LNbits Livestream extension produces a static QR code that can be shown on screen while livestreaming a DJ set for example. If someone listening to the livestream likes a song and want to support the DJ and/or the producer he can scan the QR code with a LNURL-pay capable wallet.
 
 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).
