 This module adds a new exec provider capable of executing PowerShell commands.
 
-##Module Description
+## Module Description
 
 Puppet provides a built-in `exec` type that is capable of executing commands. This module adds a `powershell` provider to the `exec` type,  which enables `exec` parameters, listed below. This module is particularly helpful if you need to run PowerShell commands but don't know the details about how PowerShell is executed, since you can technically run PowerShell commands in Puppet without the module.

 This module requires PowerShell to be installed and the `powershell.exe` to be available in the system PATH.

 The powershell module adapts the Puppet [exec](http://docs.puppet.com/references/stable/type.html#exec) resource to run PowerShell commands. To get started, simply install the module and declare 'powershell' in `provider` with the applicable command.

 When using `exec` resources with the `powershell` provider, the `command` parameter must be single-quoted to prevent Puppet from interpolating `$(..)`.

 This has the added benefit of not requiring escaping '$' in the PowerShell code. Note that the files need to have DOS linefeeds or they will not work as expected. One tool for converting UNIX linefeeds to DOS linefeeds is [unix2dos](http://freecode.com/projects/dos2unix).

 Puppet Inc modules on the Puppet Forge are open projects, and community contributions are essential for keeping them great. We can’t access the huge number of platforms and myriad hardware, software, and deployment configurations that Puppet is intended to serve. We want to keep it as easy as possible to contribute changes so that our modules work in your environment. There are a few guidelines that we need contributors to follow so that we can have a chance of keeping on top of things. For more information, see our [module contribution guide.](https://docs.puppet.com/forge/contributing.html)
