There are two methods of installing iIT. The first is to extract the zip file that contains iIT and the full Eclipse 3.4.2 development environment. The second is to install iIT into your own installation of Eclipse 3.4 or newer using the update site mechanism. Using this mechanism is out of the scope of this document but more information can be found in the Eclipse help documentation by clicking on Help and then the Help Contents menu item.

To start iIT, double click the iit.exe file found under the eclipse folder where you extracted the zip. There are many launch properties found in the iit.ini file. These properties concern mainly memory and java usage and are explained in the Eclipse docmentation.
