+## Building from Source
+
+This software builds with [SBT][http://scala-sbt.org/] (mostly because I
+can't stand Maven, and I'm tired of fighting with Gradle).
+
+If you're on a *nix box (including MacOS), simply run:
+
+```
+bin/activator compile
+```
+
+If you're on Windows, you'll have to download SBT and run
+
+```
+sbt build
+```
+
