For what is PSAppDeployToolkit\Frontend

Hello, I am currently familiarizing myself with the new version V4. There is the following folder: PSAppDeployToolkit\Frontend with the subfolders V3 and V4.
Can anyone tell me what the folders are needed for?

Looks like you downloaded the wrong file for people starting out.

Download PSAppDeployToolkit_Template_v4.zip instead. (see in red below)

And I’ll just add for anyone reading this: don’t concern yourself with what’s in the PSAppDeployToolkit folder. It’s the toolkit in of itself and needs to remain complete and unmodified to ensure proper functionality. The “Frontend” folder is for generating the templates that @That-Annoying-Guy has kindly shown to you.

the v3 and v4 folders are in the frontend folder when the pure v4 PSADT zip file is downloaded.
