+## How do I connect to my WebSocket server?
+
+This library is **NOT** a WebSockets library. This library is only for servers that implement the socket.io protocol, 
+such as [socket.io](https://socket.io/). If you need a plain WebSockets client check out 
+[Starscream](https://github.com/daltoniam/Starscream) for Swift and [JetFire](https://github.com/acmacalister/jetfire)
+for Objective-C.
+
+## Why isn't my event handler being called?
+
+One of the most common reasons your event might not be called is if the client is released by 
+[ARC](https://developer.apple.com/library/content/documentation/Swift/Conceptual/Swift_Programming_Language/AutomaticReferenceCounting.html).
+
+Take this code for example:
+
+```swift
+class SocketManager {
+    func addHandlers() {
+        let socket = SocketIOClient(socketURL: "http://somesocketioserver.com")
+        
+        socket.on("myEvent") {data, ack in
+            print(data)
+        }
+    }
+
+}
+```
+
+This code is **incorrect**, and the event handler will never be called. Because as soon as this method is called `socket`
+will be released and its memory reclaimed.
+
+A correct way would be:
+
+```swift
+class SocketManager {
+    let socket = SocketIOClient(socketURL: "http://somesocketioserver.com")
+    
+    func addHandlers() {
+        socket.on("myEvent") {data, ack in
+            print(data)
+        }
+    }
+}
+
+```
