Stable Version, from Maven
If you're using Maven, the simplest thing is to add Moo as a dependency to your project:
<dependency> <groupId>com.codiform</groupId> <artifactId>moo-core</artifactId> <version>2.0</version> </dependency>
If you're not using Maven, you can download the .jar from the Maven central repository anyway.
Development Version, from GitHub
If you'd like to be on the bleeding edge, you can download the current source repository, either as a big ZIP file or you can clone the repository from GitHub and build it yourself using Maven:
$ git clone git://github.com/geoffreywiseman/Moo.git
