+elevate=true                                                   ; Run game with admin priveleges
+
+[speedhack]

+enabled=false                                                  ; Is speedhack enabled
+
+[steam]
+enabled=true                                                   ; Is Steam support enabled
+elevate=true                                                   ; Run Steam with admin priveleges
+gameid=12927812811798609920                                    ; Game id in Steam library
+```
+

+* Create desktop shortcut for this game
+* Find new shortcut on desktop and open its properties

+* Delete shortcut if you want
+* Set the `[steam].enabled` parameter to `true`
