+### SSL Cipher Suites
+
+To use an SSL encrypted connection, you need to tell Starscream about the cipher suites your server supports. 
+
+```swift
+socket = WebSocket(url: URL(string: "wss://localhost:8080/")!, protocols: ["chat","superchat"])
+
+// Set enabled cipher suites to AES 256 and AES 128
+socket.enabledSSLCipherSuites = [TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384, TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256] 
+```
+
+If you don't know which cipher suites are supported by your server, you can try pointing [SSL Labs](https://www.ssllabs.com/ssltest/) at it and checking the results.
+
+### Compression Extensions
+
+Compression Extensions ([RFC 7692](https://tools.ietf.org/html/rfc7692)) is supported in Starscream.  Compression is enabled by default, however compression will only be used if it is supported by the server as well.  You may enable or disable compression via the `.enableCompression` property:
+
+```swift
+socket = WebSocket(url: URL(string: "ws://localhost:8080/")!)
+socket.enableCompression = false
+```
+
+Compression should be disabled if your application is transmitting already-compressed, random, or other uncompressable data.
 
 ### Custom Queue
 
-A custom queue can be specified when delegate methods are called. By default `dispatch_get_main_queue` is used, thus making all delegate methods calls run on the main thread. It is important to note that all WebSocket processing is done on a background thread, only the delegate method calls are changed when modifying the queue. The actual processing is always on a background thread and will not pause your app.

To do this, in Xcode, navigate to the target configuration window by clicking on the blue project icon, and selecting the application target under the "Targets" heading in the sidebar. In the tab bar at the top of that window, open the "Build Phases" panel. Expand the "Link Binary with Libraries" group, and add `Starscream.framework`.

+## KNOWN ISSUES
+- WatchOS does not have the the CFNetwork String constants to modify the stream's SSL behavior. It will be the default Foundation SSL behavior. This means watchOS CANNOT use `SSLCiphers`,  `disableSSLCertValidation`, or SSL pinning. All these values set on watchOS will do nothing. 
+- Linux does not have the security framework, so it CANNOT use SSL pinning or `SSLCiphers` either. 
+
+
 ## TODOs
 
-- [ ] WatchOS?
-- [ ] Linux Support?
-- [ ] Add Unit Tests - Local Swift websocket server
+- [ ] Add Unit Tests - Local WebSocket server that runs against Autobahn
