+.SYNOPSIS
+ A simple Powershell script to download and install a salt minion on windows.
+
+.DESCRIPTION
+ The script will download the official salt package from saltstack. It will
+ install a specific package version and accept parameters for the master and
+ minion ids. Finally, it can stop and set the windows service to "manual" for
+ local testing.
+
+.EXAMPLE
+ ./bootstrap-salt.ps1
+ Runs without any parameters. Uses all the default values/settings.
+
+.EXAMPLE
+ ./bootstrap-salt.ps1 -version 2015.4.1-3
+ Specifies a particular version of the installer.
+
+.EXAMPLE
+ ./bootstrap-salt.ps1 -runservice false
+ Specifies the salt-minion service to stop and be set to manual. Useful for
+ testing locally from the command line with the --local switch
+
+.EXAMPLE
+ ./bootstrap-salt.ps1 -minion minion-box -master master-box
+ Specifies the minion and master ids in the minion config. Defaults to the
+ installer values of host name for the minion id and "salt" for the master.
+
+.EXAMPLE
+ ./bootstrap-salt.ps1 -minion minion-box -master master-box -version 2015.5.2 -runservice false
+ Specifies all the optional parameters in no particular order.
+
+.PARAMETER version
+ Default version defined in this script.
+
+.PARAMETER runservice
+ Boolean flag to start or stop the minion service. True will start the minion
+ service. False will stop the minion service and set it to "manual". The
+ installer starts it by default.
+
+.PARAMETER minion
+ Name of the minion being installed on this host. Installer defaults to the
+ host name.
+
+.PARAMETER master
+ Name or IP of the master server. Installer defaults to "salt".
+
+.PARAMETER repourl
+ URL to the windows packages. Default is "https://repo.saltstack.com/windows"
+
+.NOTES
+ All of the parameters are optional. The default should be the latest
+ version. The architecture is dynamically determined by the script.
