1. Install/Upgrade carthage package manager (e.g. using brew or pkg) - link to github repo
2. Create a new Cocoa/Swift app
3. Create a new file called `Cartfile` in the application folder
4. Add `github "moozzyk/SignalR-Client-Swift" master` to the file to get the latest version (releases, tags in the future)
5. Run `carthage update --platform macOS` (--platform can be skipped to install for iOS and tvOS)
6. Add SignalRClient and SockertRocket to "Embedded Binaries" 
7. Add SignalRClient and SocketRocket to "Linked Frameworks and Libraries" (Note 6. should do this automatically)
8. Add `import SignalRClient` to import SignalR client definitions
9. When using http you will likely see this error:
   SignalRApp[14409:1752344] App Transport Security has blocked a cleartext HTTP (http://) resource load since it is insecure. Temporary exceptions can be configured via your app's Info.plist file.

Documentation
 - lacking, samples very hard to find
 - http://caml.inria.fr/pub/docs/manual-ocaml/libref/Str.html - initally confusing than helpful
~~Regular expressions - match groups~~
~~Basis IO operations - too complicated/missing~~

Good documentation/starting guide
Should have read more before starting (e.g. the borrowing concept)
unwrap().unwrap().unwrap() everywhere (likely I am doing something wrong)
iter() vs into_iter() confusing for beginners
regex - quite easy to get it up and running
when is ';' (not) required?
lack of traditional `for` loop - counter needs to be in the loop
pattern matching
lifetimes/borrows are killing me - day 4 - could not return HashMap from a function
hint in errors are helpful:
