One needs to install JRE or JDK version 6 from http://www.java.com if Java is not available. Note that JDK is preinstalled on Mac OS X and available via package manager on many Linux systems.

Put following jars in your classpath:

• scala-library.jar (Scala standard library). Please make sure the version is at least 2.8.1.
• SWT (The Standard Widget Toolkit). Please get the latest version from here

UniChess is built using sbt. Therefore to compile, test, and run UniChess from a developer's point of view, one needs to install JDK, Scala, and sbt, then use sbt commands like sbt update to pull all the dependencies. For further information on usage of sbt, please consult relevant pages.

The author got lots of help from open source Chess software like Stockfish, Crafty, and Scid. For opening repertoire preparation, Chess Position Trainer teaches the author a lots about how such task could be handled by software. Last but not the least, Shannon's seminal paper, Chess Programming Wiki and Wikipedia are invaluable sources to understand chess programming.
