+### Building
+
+Build with
+
+    lein uberjar
+
+This will build a jar file in `target/uberjar/beowulf-VERSION-standalone.jar`,
+where VERSION is the current version number.
+
+On UNIX platforms (includeing Linux), you can build a standalone binary by 
+invoking a script, `resources/sh/builder.sh`, *after* invoking `lein uberjar`, 
+so:
+
+    lein uberjar
+    sh resources/sh/builder.sh
+
+This should build a standalone binary in `target/beowulf`.
+
+In order to be able to invoke this binary just like any other program, move it
+to somewhere on your path, idealy `${HOME}/bin` or `/usr/local/bin`.
