 Trajectories used in [How Resilient are Imitation Learning Methods to Sub-Optimal Experts?]()
 
 These trajectories are formed by using [Stable Baselines](https://stable-baselines.readthedocs.io/en/master/).
-Each file is a dict of a set of trajectories with the following keys:
+Each file is a dictionary of a set of trajectories with the following keys:

+* rewards: reward retrieved after the action in the given timestamp `t`
 * episode_returns: The aggregated reward of each episode (each file consists of 5000 runs)
 * episode_Starts: Whether that `obs` is the first state of an episode (boolean list).
