 Next steps:
 
-1. Disable any existing display managers (IMPORTANT):
+1. Enable the greeter:
-     sudo systemctl disable gdm sddm lightdm
+     dms greeter enable
+     (This will automatically disable gdm, sddm, or lightdm display managers,
+      set graphical.target, and enable greetd)
 
-2. Enable greetd service:
+2. Sync your theme with the greeter (optional):
-     sudo systemctl enable greetd
+     If you have DankMaterialShell (DMS) installed, you can sync theming with:

-3. (Optional) Sync your theme with the greeter:
-     If you have DankMaterialShell (DMS) installed, you can sync with:
      dms greeter sync
 
-     Check sync status: dms greeter status
+3. Check your setup:
-     Then logout/login to see your wallpaper on the greeter!
