 The first step is to unblock the download package containing PowerTab. This can be done from Windows Explorer by Right-Clicking on **PowerTab-<version>.zip** and selecting **Properties**. Then click on the **Unblock** button near the bottom of the properties dialog. Finally, press **OK**.
 
 The second step is to extract the PowerTab package using your favorite archiving utility to your PowerShell modules folder. The default location for this is `.\WindowsPowerShell\Modules` (relative to your **Documents** folder). You may instead extract PowerTab to another folder on your `$env:PSModulePath`.
