+# Simple Build System
+
+This is a simple build system based around makefiles & shell scripts. To adapt this system to your own project you will need to edit the following files:
+
+- file-list.txt
+- version.txt
+- makefile
+
+When you call make, the makefile will call make in the src directory with the target make rule. So if you modify the target rule, that will be called. All of the files in file-list.txt will be copied from the left path to the right path in the build directory.
