Import posh-git module to an existing console (non Git Shell)

gistfile1.ps1

# Starting a new PowerShell (PS) console on a Windows OS instance that has GitHub client for Windows installed ...

# Find the local instance of git.exe; it's an 'external' dependency for posh-git
Get-ChildItem -Path $env:LocalAppData\GitHub\ -Filter git.exe -Recurse

# Should return at least 1 instance of git.exe
# Select one and add an alias to it
# I choose the one in \bin\ for example:

New-Alias -Name git -Value $env:LOCALAPPDATA\GitHub\PortableGit_c2ba306e536fdf878271f7fe636a147ff37326ad\bin\git.exe

# I then use tab auto-complete to find the latest posh-git module, as included with the GitHub client for Windows
Import-Module $env:LocalAppData\GitHub\PoshGit_869d4c5159797755bc04749db47b166136e59132\posh-git.psm1

Any idea how to have "GitHub client for Windows installed" ? Without installing GitHub Desktop. Thanks.
