-- python modules that provide classes for trajectories and moving objects (objects with some characteristics and a trajectory)
+- python modules that provide classes for trajectories and moving objects (objects with some characteristics and a trajectory), as well as some basic code for simple traffic engineering problems (fundamental diagram and traffic signal timing). 
 
-Example:
+An Example:
 
 The main use case and example for now is to load and analyze trajectory data from the NGSIM project (ngsim-community.org). In a ipython shell with the pylab option, you can try the following (once the python modules are in your python path). 
 
-import storage
-objects = storage.loadNgsimFile('./trajectories-0400-0415.txt',100)
-for o in objects: o.draw()
+$ import storage
+$ objects = storage.loadNgsimFile('./trajectories-0400-0415.txt',100)
