To install blue, you should download the latest installer .jar file from the blue Sourceforge page here . To run the installer on Windows or OSX, simply double-click the jar file. For Linux or if your system does not have .jar files associated with java, you should open up the commandline, change directories to where the jar file is, then type:
java -jar blue_0.111.0_installer.jar
The name of the installer jar may differ from the above to reflect the current version number. When the installer opens up, you should be greeted by a screen that looks like this:

You will have to agree to the license, then blue will install to the directory chosen by the user. To run blue, you should open the directory where blue was installed, then go into the bin directory. Included in the bin directory are a Windows batch file(blue.bat), a Linux/OSX shell script(blue.sh), and a MacOSX command script (blue.command). Click on the apropriate file to start blue.

Unless you are using a mouse that emulates a second mouse button, you will have to use a combination of the "open apple" key plus a mouse click for all "rt-clicks" that are mentioned in this documentation.
To make use of the function key shortcuts (F1-F12), you will also need to tick System Preferences, Keyboard and Mouse, "F1-F12 to control software features". (This affects recent versions of OSX.)
