 #Getting Started
 
 The first thing we need to do is setup the tools required to build and run an application. We will start out by getting the [K Version Manager (KVM)](https://github.com/aspnet/Home/wiki/version-manager)
 
 * Clone the repository
-* On the command line execute ```kvmsetup.cmd``` 
+* On the command line execute
+ * ```kvmsetup.cmd``` on Windows or
+ * ```sh kvmsetup.sh && source ~/.kre/kvm/kvm.sh``` on OSX/Linux
 * This command will setup your environment, getting it ready to install a version of the runtime. It adds kvm to your path and puts it in your user profile.
 * Execute ```kvm install 0.1-alpha-build-0421```. This command will download the named version of the KRE and put it on your user profile ready to use. You can get the latest version by running ```kvm upgrade``` but 0421 was the last version explicitly tested. see the [KVM page](https://github.com/aspnet/Home/wiki/version-manager) for more information on KVM.
 * Navigate to samples\ConsoleApp
 * Run ```kpm restore```. This downloads the System.Console package so the app can do Console.WriteLine
-* Run ```K run```
+* Run ```k run```
 * You should see a message saying "Hello World"
-* Type ```SET KRE_TRACE=1```
-* Run ```K run```
+* Type
+ * ```SET KRE_TRACE=1``` on Windows or
+ * ```export KRE_TRACE=1``` on OSX/Linux
+* Run ```k run```
 * You should now see compiler output as well as the "Hello World" message

 #Switching to Core CLR

 By default when running the applications you are running against Desktop CLR (4.5), you can change that using the KVM command.
 
 1. Run ```kvm install 0.1-alpha-build-0421 -svrc50``` This command gets the latest Core CLR version of the k runtime and sets it as your default. The -svrc50 switch tells it to use Core CLR, you can use -svr50 to target desktop again.

 **NOTE: There are going to be parts of the stack that work on Desktop but do not work on Core CLR. This set should get smaller and smaller as time goes on, but it is entirely likely as you use Core CLR you will hit errors that can't be worked around as the Core CLR surface area just does not exist yet.**
 
+**NOTE: There is no Core CLR currently on OSX/Linux. There is only a single platform (mono45) and a single architecture (x86).**

 #Core CLR Packages
 
 Currently the BCL is split into some fairly fine grained packages, which was one of the goals of this effort. However, the packages that exist today do not necessarily represent the list of packages that we will end up with. We are still experimenting with what makes sense to be a package and what the experience should be.
