+
+For information installing Powershell click [here](https://docs.microsoft.com/en-us/powershell/scripting/install/installing-powershell?view=powershell-7.1).
+
+Once Powershell is installed you will need to install the Pester module by running the following command in Powershell:
+
+    PS> Install-Module Pester
+
+The following steps assume that you are in the same directory as the test suite.
+
+Run the test suite. It's written using the Pester framework, and can be
+run with powershell:
+
+    PS> Invoke-Pester
+
+This will fail. To fix it, open up the HelloWorld.ps1 file and add the following code:
+
+    ```
+    function Get-HelloWorld {
+        return "Hello World!"
+    }
+    ```
+
+Run the test again.
+
+## Submit

+When everything is passing, you can submit your code with the following
+command:
