+## For submodule developers
+
+Depending on the submodule that you develop in, you might want to run things out of the submodule.
+For example, `boom` has its own Generator, package, top module, and configurations separate from
+the `example` package in `src/main/scala`. Thus, to build a `boom` project you do something like
+the following:
+
+    make SBT_PROJECT=boom PROJECT=boom.system CONFIG=<BOOM Config to use> TOP=ExampleBoomSystem
+
+However, that is very long to write everytime there is a compile. Thus, a shorthand way to build
+the subproject is the following:
+
+    make SUB_PROJECT=boom CONFIG=<BOOM Config to use>
+
+This sets the proper configuration flags for make to work correctly.

+Currently, the supported `SUB_PROJECT` flags are:
