-## Suggested Quality Management
-This section describes guidelines put in place to maintain a standard of quality while also promoting broader contribution.
-### General Best Practices
-### Resource Naming
-* Give the resource a name that is indicitive of the actions and/or results of its running
-
-### Fault Handling
-* Every submitted resource should include basic fault handling. One of many good write-ups can be found via Microsoft’s Hey, Scripting Guy! Blog: https://blogs.technet.microsoft.com/heyscriptingguy/2014/07/09/handling-errors-the-powershell-way/
-
-### Alias Usage
-* Avoid any alias usage within all submitted resources.
-
-### Global Variable Usage
-* Avoid changing any global variables
-
-### Help Information
-* All resources shall have inline documentation. 
-
-### Scripts
-* The script should be easy to read and understand
-* Place user-defined variables towards the top of the script
-
-### Modules
-* The module file, PSM1, should contain only functions. A module manifest file, PSD1, should also be created and included. A module formatting file (format.ps1xml) is desirable but not a requirement.  
-* Use only standard verbs
-
-### Security
-* Usage of PowerShell’s strict mode is preferred, but not required. 
-* Remove any information related to one’s own environment (examples: Passwords, DNS/IP Addresses, custom user credentials, etc)
-
-## Resource Maintenance
-### Maintenance Ownership
-Ownership of any and all submitted resources are maintained by the submitter. This ownership also includes maintenance of any and all submitted resources. 
-### Filing Issues
-Any bugs or other issues should be filed within GitHub by way of the repository’s Issue Tracker. 
-### Resolving Issues 
-Any community member can resolve issues within the repository, however only the owner or a board member can approve the update. Once approved, assuming the resolution involves a pull request, only a board member will be able to merge and close the request.

+### General Best Practices
+### Resource Naming
+* Give the resource a name that is indicitive of the actions and/or results of its running
+
+### Fault Handling
+* Read and apply the following basic fault handling where applicable: Microsoft’s Hey, Scripting Guy! Blog: https://blogs.technet.microsoft.com/heyscriptingguy/2014/07/09/handling-errors-the-powershell-way/
+
+### Alias Usage
+* Avoid any alias usage within all submitted resources.
+
+### Global Variable Usage
+* Avoid changing any global variables
+
+### Help Information
+* All resources should have inline documentation. 
+
+### Scripts
+* The script should be easy to read and understand
+* Place user-defined variables towards the top of the script
+
+### Modules
+* The module file, PSM1, should contain only functions. A module manifest file, PSD1, should also be created and included. A module formatting file (format.ps1xml) is desirable but not a requirement.  
+* Use only standard verbs
+
+### Security
+* Usage of PowerShell’s strict mode is preferred, but not required. 
+* Remove any information related to one’s own environment (examples: Passwords, DNS/IP Addresses, custom user credentials, etc)
+
+## Resource Maintenance
+### Maintenance Ownership
+Ownership of any and all submitted resources are maintained by the submitter. This ownership also includes maintenance of any and all submitted resources. 
+### Filing Issues
+Any bugs or other issues should be filed within GitHub by way of the repository’s Issue Tracker. 
+### Resolving Issues 
+Any community member can resolve issues within the repository, however only the owner or a board member can approve the update. Once approved, assuming the resolution involves a pull request, only a board member will be able to merge and close the request.

+.SYNOPSIS
+Retrieve the total thin provisioned space on each datastore.

+.DESCRIPTION
+Intended to reveal provisioned space alongside total/free space, to assist with svMotion decisions.
+-Name should be supplied from the pipeline via Get-Datastore.
+
+.EXAMPLE
+Get-Datastore | Get-DatastoreProvisioned | Format-Table -AutoSize
+View all datastores and view their capacity statistics in the current console.
+
+.EXAMPLE
+Get-Datastore -Name '*ssd' | Get-DatastoreProvisioned | Where-Object -Property ProvisionedPct -ge 100
+For all datastores ending in 'ssd', return the capacity stats of those at least 100% provisioned.
