Catalogs provide all the information that OSBuilder needs for applying Microsoft Updates to an Operating System.
To know which catalogs OSBuilder needs to download, it pulls a master Content JSON file from GitHub
This file is copied to the Updates directory in Content
And tells OSBuilder which Update Catalog XML files to download
The Catalog XML files are then copied into an Updates Category subdirectory and is then used by OSBuilder to know which Microsoft Updates to download and apply
WSUS provides the content for the Catalogs, and I simply use PowerShell to export the information after reviewing it for errors
