-# Installation Instructions
+# AutoTx Service Installation
+
+The AutoTx service doesn't have a *conventional* installer but rather has to be
+registered using the `InstallUtil.exe` tool coming with the .NET framework.
+
+## Using The Installation Script
+
+A PowerShell script to help with the installation is provided with each AutoTx
+package. To use the script, follow these steps:
+
+- Log on to the computer using an account with adminstrative privileges.
+- Edit the `ScriptsConfig.ps1` settings file, adjust the values according to
+  your setup.
+- Open a PowerShell console using the `Run as Administrator` option. The script
+  [Run-ElevatedPowerShell.ps1](Scripts/Run-ElevatedPowerShell.ps1) can  be used
+  to start a shell with elevated permissions.
+- Navigate to the installation package directory, run the `Install-Service.ps1`
+  script.
+- Supply the two required configuration files in the `conf/` subdirectory of
+  the service installation location and start the service using `Start-Service
+  AutoTx`.
+
