 ## How this works
 
-The custom script extension for VMSS can download a script and execute it on a VMSS node. The install-AzurePowershell.ps1 script is the script you run to update the VMSS model with this extension. The install-dotnetcore.ps1 script is the script that's downloaded to the VMSS node and executed to do the install. The install-dotnetcore.ps1 also adds the install directory to the system path.

 ## How to use the extension
 
-1. Upload the install-dotnetcore.ps1 file to a storage account (or use the version I'm hosting - but don't rely on it being stable :-)). You can secure the script location and provide the key via the custom script extension: https://docs.microsoft.com/en-us/azure/virtual-machines/extensions/custom-script-windows
+1. In the Install-DotnetRuntimeVMSS.ps1 file, you can add parameters to the `$commandToExecute` variable, which will control the version, release channel and install directory for dotnet. Use this for reference: https://github.com/dotnet/docs/blob/master/docs/core/tools/dotnet-install-script.md.
