Convert old ADM template to ADMX

I'm having an issue with an old ADM file that needs to be converted to ADMX.
I have no idea about what to do to accomplish this.

The ADM looks like this:
CLASS USER
CATEGORY !!WindowsComponents
 CATEGORY !!InternetExplorer
  CATEGORY !!InternetControlPanel
   CATEGORY !!SecurityPage
    CATEGORY !!InternetZone
     POLICY "Launching Applications and Unsafe Files"
      KEYNAME "Software\Policies\Microsoft\Windows\CurrentVersion\Internet Settings\Zones\3"
      EXPLAIN !!Launch
      PART 1806 DROPDOWNLIST REQUIRED
        VALUENAME "1806"
        ITEMLIST
	       NAME !!Enabled VALUE NUMERIC 0
	       NAME !!Prompt VALUE NUMERIC 1 DEFAULT
	       NAME !!Disabled VALUE NUMERIC 3
	END ITEMLIST
      END PART
     END POLICY
    END CATEGORY
