+### Creating WebSocket Connections:
+To use WebSockets, create a `libcurl.WebSocket` object, which works identically to the regular [WebSocket](https://developer.mozilla.org/en-US/docs/Web/API/WebSocket) object.
+```js
+let ws = new libcurl.WebSocket("wss://echo.websocket.org");
+ws.binaryType = "arraybuffer";
+ws.addEventListener("open", () => {
+  console.log("ws connected!");
+  ws.send("hello".repeat(128));
+});
+ws.addEventListener("message", (event) => {
+  let text = new TextDecoder().decode(event.data);
+  console.log(text);
+});
+```
