+There is a possibility that even when running from a docker container, the installation of `qemu-user-static` will silently fail when building the image because `binfmt-support` _must be enabled on the underlying kernel_. An easy fix is to ensure `binfmt-support` is installed on the host machine before starting the `./build-docker.sh` script (or using your own docker build solution).

 The build of Raspbian is divided up into several stages for logical clarity

+
+### 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).
+
+```
+# Example for building a lite system
+$ touch ./stage3/SKIP ./stage4/SKIP
+$ rm stage4/EXPORT*
+```
+If you wish to build further configurations upon (for example) the lite system, you can also delete the contents of `./stage3` and `./stage4` and replace with your own contents in the same format.
