PowerShell Configuration

To setup your PowerShell to match mine, simply run the following commands:

# You may need to run this in an administrative PowerShell instance
Set-ExecutionPolicy Unrestricted

$SetupScript = Invoke-WebRequest https://gist.githubusercontent.com/notheotherben/77ccb460948afd826365e85d226509a7/raw/setup.ps1
$ScriptBlock = [ScriptBlock]::Create($SetupScript.Content)
Invoke-Command -ScriptBlock $ScriptBlock

Features

• Installs Hack on your system (a really nice monospace font-face)
• Installs PoshGit to give you useful information about Git repos from your PowerShell.
• Installs the Afterglow colour scheme in your terminal.
• Configures your prompt to look a bit cleaner especially when dealing with long paths.
