A Quicklook plugin for the questionably abbreviated "Flexible and Interoperable Data Transfer" (.FIT) files, created by devices like the Garmin Edge 500

Copy the QLFit.qlgenerator file to ~/Library/QuickLook/

To do this (based on OS X 10.7):

• In the Finder menu bar click "Go > Go to folder.."
• Enter ~/Library
• Find or create a QuickLook folder
• Drag the QLFit.qlgenerator into this folder

If it doens't seem to work, you could try running the command qlmanage -r in a terminal (or rebooting, if it's easier)

Open the Xcode project, and click build.

Whatever I am currently running, currently OS X 10.7
