+Build Instructions
+------------------
+
+The root directory of the project contains the SBT launcher, shell script, and Windows command script.
+
+This is the directory structure of the build.
+
+|- project +
+|          |-build +
+|          |       |- kata.scala             Project Definition, containing module structure, compiler
+|          |       |                         options, cross module dependencies, etc.
+|          |       |- build.properties       Version of SBT, Scala, and Kata
+|          |                                 A different version of Scala is used to run SBT and compile
+|          |                                 the Project Definition than is used to compile Kata
+|          |-target                          Compiled Project Definition
+|          |
+|          +-boot                            Versions of Scala Compiler and Library.

+|-target +
+         |- <scala version M>    All built artifacts (classes, jars, scaladoc) for module N
+                                 built for version M of Scala.
+
+1. ./sbt update (this step is required after a fresh checkout, after changing the version of
+                 SBT, Scala, or other dependencies)
+2. ./sbt [compile | package | test-compile | test | publish-local | publish]
+
+For continuous compilation:
+
+$ ./sbt
+> ~ compile
+
