+### Stage specification
+If you wish to build up to a specified stage (such as building up to stage 2 for a lite system), place an empty file named `SKIP` in each of the `./stage` directories you wish not to include.
+
+Then remove the `EXPORT*` files from `./stage4` (if building up to stage 2) or from `./stage2` (if building a minimal system).
