	if ($null -eq $Modules) {
		return
	}

	$psModules = './ps_modules'

	# download modules to ps_modules
	$Modules.psobject.properties.name | ForEach-Object {
		$_name = $_
		$_version = $Modules.$_name.version
		$_repository = if ([string]::IsNullOrEmpty("$($Modules.$_name.$_repository)")) { 
			'psgallery' 
		} else {
			[string]"$($Modules.$_name.$_repository)" 
			}

		try {
			# if version is latest, retrieve current
			if ($_version -ieq 'latest') {
				$_version = [string]((Find-Module -Repository $_repository -Name $_name -ErrorAction Ignore).Version)
			}

			Write-Host "=> Downloading $($_name)@$($_version) from $($_repository)... " -NoNewline -ForegroundColor Cyan

			# if the current version exists, do nothing
			if (!(Test-Path (Join-Path $psModules "$($_name)/$($_version)"))) {

https://badgerati.github.io/Pode/Getting-Started/LocalModules/ states that only the default PSGallery is supported, but custom repositories can easily be supported by adding the repository name to the 'ps_modules' file and to the setup.ps1 file

Additional Details

Modified ps_modules file content example:
{ "modules": { "eps": {"version": "0.5.0", "repository": "psgallery" } }, "devModules": { "pester": {"version": "latest", "repository": "psgallery" } } }

Yes, originally this was only meant to just be basic support - but adding in custom repositories is all right.

Looking at the change it does require the ps_modules section in the package.json file to change 🤔 so the function will need to support the old and new (something like: if $Modules.$_name.version is null then assume original format and default to PSGallery)
