 # System.Net Test Prerequisites
 Contains source files for the networking test servers in Azure or a private IIS deployment.
-
-## Deployment Instructions for a private multi-machine environment
-
-### Configuration
-
-1. Open .\Deployment\config.ps1 in an editor.
-2. Fill in the _Machine Selection_ section with the names and IP addresses of the target machines. In most cases the default options for _Test Parameters_ should be enough.
-
-Note: the `config.ps1` file has been added to .gitignore to prevent it being updated in the main branch.
-
-### Build the server applications
-
-Prepare the $DOTNET_TEST_NET_CLIENT_Machine as any Dev station following the instructions at https://github.com/dotnet/runtime/blob/main/docs/workflow/requirements/windows-requirements.md. Ensure that you can build and test CoreFX on this machine.
-In addition, you will also need to install the _Azure development_ workload for Visual Studio 2017.
-
-From a Visual Studio command prompt:
-
-```
-    powershell
-    cd .\Servers
-    .\buildAndPackage.ps1
-```
-
-You should now find a folder named `IISApplications` within the Deployment folder.
-
-### (only once) Create the Active Directory and join all machines
-
-Skip this step if previously completed and all machines are already part of a domain to which you have Administrator rights.
-This will join all machines to a test Active Directory and enable Windows Remoting.
-
-1. Copy the Deployment folder to each of the machines.
-2. Run the .\setup.ps1 script on the machine designated to become the Domain Controller. Once complete, the machine will reboot.
-3. Run the .\setup.ps1 script on all other domain joined machines. Once complete, the machines will reboot.
-
-### Install or Update the environment
-
-Running as the Active Directory Administrator, run .\setup.ps1 from any of the machines within the environment.
-The script will use WinRM to connect and update all other roles.
