"or the appropriate subdirectory within XAMPP launcher"

Hi,

From: https://portableapps.com/apps/development/xampp

"XAMPP isn't in PortableApps.com Format, but it easily integrates with the PortableApps.com Menu by using the XAMPP Launcher (linked above) and installing XAMPP in the root directory of your portable device or the appropriate subdirectory within XAMPP launcher. You can open the zip/7z archive of the portable version with 7-Zip Portable."

Ok root directory is obvious, but please what does " or the appropriate subdirectory within XAMPP launcher" actually mean?
Where would that be please?
Straight into PortableApps\XAMPP or where in?...

PortableApps\XAMPP
├───App
│ └───AppInfo
├───Data
└───Other
├───Help
│ └───images
└───Source

Do you create a new directory undrer PortableApps\XAMPP or unzip into an existing one?

Thanks,
Paul
