+.DESCRIPTION
+Script downloads installer for the software.
+Since (in most cases) we aren't allowed to redistribute the installers, a script to download them on demand is provided instead.
+
+To use, fill out the parameters in the script, so all you need to do is run ./download.ps1
+
+For GitHub Releases that change, a script is provided in /scripts/Get-LatestGitHubRelease.ps1 to get the latest link which you can pass in via -URI.
+
+(this download script could probably be improved later down the line across the board)
+
+.EXAMPLE
+# Get the latest ARM version of PowerShell
+$URI = (& '../../Scripts/Get-LatestGitHubRelease.ps1' -Repo 'PowerShell/PowerShell' -Filter {$_.name -like '*win-arm64.msi'}).DownloadURI,
+./download.ps1 -URI $URI -OutFileName 'ps7-win-arm64.msi'
+#>

+    [uri]$URI = (& (Join-Path $PSScriptRoot '../../scripts/Get-LatestGitHubRelease.ps1') -Repo 'git-for-windows/git' -Filter {$_.name -like '*64-bit.exe'}).DownloadURI,
+    [Parameter()]
+    [string]$OutFileName = 'Git-Installer.exe'
