Create SharePoint environments with AutoSPInstaller

Yo Pros! We have found this fantastic tool to help setup farms quickly that we had to share with you!

It’s our fifth project now requiring multiple SharePoint farms to support the ALM process for Dev, Test, Production; which was needed to built quickly whilst maintaining best practice and consistency.
