-The embedded tweaks handle OS-level stuff during install. Bootstrap handles app installation via WinGet and Sophia Script tweaks.
+Install-time tweaking is intentionally minimal. Bootstrap handles app installation via WinGet and system customization via Sophia Script after first login.
 
 **If bootstrap fails or you want to re-run it:** Just run `C:\Setup\bootstrap.ps1` manually.
 
 ## Customization
 
-All the tweaks are defined in the `<Extensions>` section at the bottom of the XML file. The scripts are embedded directly in the XML.
-
-**To add a tweak:** Edit the relevant script section (Specialize.ps1, DefaultUser.ps1, or UserOnce.ps1)
-
-**To remove a tweak:** Delete or comment out the script block
-
-**To add/remove bloatware:** Edit the `$selectors` array in RemovePackages.ps1
+This file is intentionally minimal. If you add more install-time customization later, keep it small and retest Setup carefully.
