 ## Create the build event commands
 
-The build event commands can include any command that is valid at a command prompt or in a *.bat* file. The name of a batch file should be preceded by `call` to ensure that all subsequent commands are executed. The batch file itself runs from the output folder, for example, `bin/Debug`. If you need the same batch file for all configurations, you could put it in the same folder as the project file and use a relative path to it, for example, `call ../../prebuild.bat`.
+The build event commands can include any command that is valid at a command prompt or in a *.bat* file. Available commands are listed in the [Windows command reference](/windows-server/administration/windows-commands/windows-commands). The name of a batch file should be preceded by `call` to ensure that all subsequent commands are executed. The batch file itself runs from the output folder, for example, `bin/Debug`. If you need the same batch file for all configurations, you could put it in the same folder as the project file and use a relative path to it, for example, `call ../../prebuild.bat`.
 
 You can execute [PowerShell](/powershell/scripting/overview) scripts by entering a command like `PowerShell MyPowerShellScript.ps1`. The path to the PowerShell script may be absolute, or may be relative to the project directory. You would need to make sure that the execution policy for PowerShell scripts on your operating system is set appropriately in order to run the script. See [About execution policies](/powershell/module/microsoft.powershell.core/about/about_execution_policies).
