+## Resources for using the Qualisys Project Automation Framework (PAF)
+
+The purpose of the ***Project Automation Framework*** (PAF) is to streamline the motion capture process from data collection to the final report. This repository contains an example project that illustrate how PAF can be used to implement custom automated data collection in [Qualisys Track Manager (QTM)](http://www.qualisys.com/software/qualisys-track-manager/), and how QTM can be connected to a processing engine.
