Install Apache Tomcat for your platform. Using Homebrew works well for OS X.

To find the catalina $HOME directory:

$ catalina -h

On OS X, the output might include:

Using CATALINA_HOME:   /usr/local/Cellar/tomcat/7.0.37/libexec

Clone this repository to the webapps directory of CATALINA_HOME.

Start the Tomcat server:

$ catalina run

Assuming the default Tomcat settings and folder name of this repository, you should be able to access the application at

http://localhost:8080/COMP6006BugTracker/app/
