  - This script (https://github.com/PowerShellCrack/Get3rdPartySoftware) will update the folder and script versions (see its list)
  - Logs most applications to _SMSTSLogs\AppLogs
 
- ## Steps:
+## Steps:
 
   1. Use 3rdPartyDownload script (https://github.com/PowerShellCrack/Get3rdPartySoftware) to download the software 
 
   2. Run MDTApplicationUpdater script (https://github.com/PowerShellCrack/MDTApplicationUpdater/tree/master) and point it to the place the first script downloaded the software to. This will update MDT's application.xml and corresponding wsf scripts versions
    NOTE: make sure your MDT application is labeled by the product name and architecture. eg. Java x64
 
+## Usage:
+ - Build MDT applications and use command: cscript Install-<name>.wsf /arch:x64|x86
+ - the <b>/arch</b> parameter are used fro applications that has both architectrue versions available. For intance, you can install Office 2016 32-bit or 64-bit on a 64-bit Windows. I have a application that has both version, but in different folders. To sepecify the right folder with writing two scripts I use the <b>/arch</b> parameter. 
+ - If no <b>/arch</b> parameter is specified, it will use the OS architecture variable and if that can't be determined (not using MDT/SCCM), it defaults to x86
+ 
+        eg. cscript Install-Office.wsf /arch:x86
+
 ## Future:
 In time I want to get updates from all the 3rd party applications that I can think an enterprise use (including office updates)
