 ### Data collection
 
 ExpMngr automates the process of collecting behavioural and movement data. **Behavioural data** is collected with 1 row per `Trial`, and automatically records some values such as the timestamp of the start and end of the trial.
-**Movement data** is the position and rotation of any object in the scene, which is captured at whatever frame rate the application is running at (in the `Update()` loop). This can be used to track positions of user controlled objects (such as hands or head in a virtual reality application) or an arbitrary object in the scene (e.g. some kind of stimuli). 
+**Movement data** is the position and rotation of any object in the scene, which is captured at whatever frame rate the application is running at (in the `Update()` loop) by adding a `Tracker` component to a GameObject. This can be used to track positions of user controlled objects (such as hands or head in a virtual reality application) or an arbitrary object in the scene (e.g. some kind of stimuli). 
 Data is stored in CSV files with automatic handling of file & directory naming.
