Zorro is a Hackystat application, and so "installing" Zorro as a user really means setting up your Hackystat account and sensors in a manner that enables the Zorro analysis commands in Hackystat to function correctly.
Use a Zorro-compliant IDE. Currently, only the Eclipse IDE has a Hackystat sensor that is designed to collect development events suitable for Zorro processing.
Install and enable the Eclipse Hackystat sensor. Chapter 2, Client-side configuration: Tool sensor installation provides an overview on Hackystat sensor installation, and Section 26.11, “Eclipse” provides instructions on installing the Eclipse sensor.
Define a Hackystat Project to be associated with your TDD development practice. Chapter 3, Server-side configuration: User account registration and preferences provides instructions on how to define a Hackystat project, which specifies how to associate sensor data into collections called "Projects" based upon the directory locations you were working in at the time.
Note that the above installation process assumes that an administrator has already installed and made available a Hackystat server configured to include the hackyApp_Zorro module. If you do not wish to download and install your own server, you can use the public Hackystat server which includes the Zorro application.
