 ## Installation
 Requires Swift 4/5 and Xcode 10.x

-If you need Swift 2.3 use the [swift2.3 tag](https://github.com/socketio/socket.io-client-swift/releases/tag/swift2.3) (Pre-Swift 4 support is no longer maintained)
-
-If you need Swift 3.x use v11.1.3.

+# Upgrading from v15 to v16
+
+This guide will help you navigate the changes that were introduced in v16.
+
+## Objective-c is no longer supported. You must now use Swift.
+
+## Client supports multiple socket.io versions
+
+The client now supports socket.io 3 servers. This is mostly a transparent change, however if your server
+is socket.io 2, you must send `.version(.two)` as an option to the manager.
+
+```swift
+SocketManager(socketURL: URL(string:"http://localhost:8087/")!, config: [.version(.two)])
+```
+
+## How to upgrade
+
+- first, upgrade the Socket.IO server to v4 with the compatibility mode enabled (`allowEIO3: true`)
+- then, upgrade the clients to v16
+- finally, once all clients have upgraded, disable the compatibility mode
+
+You can check the version of the connection on the server side with:
+
+```js
+io.on("connection", (socket) => {
+  // either 3 for the 3rd revision of the protocol (Socket.IO v2) or 4 for the 4th revision (Socket.IO v3/v4)
+  const version = socket.conn.protocol;
+});
+```
