+
+## Overview
+
+Official codebase for [Decision Transformer: Reinforcement Learning via Sequence Modeling](https://sites.google.com/berkeley.edu/decision-transformer).
+Contains scripts to reproduce experiments.
+
+![image info](./architecture.png)
+
+## Instructions
+
+We provide code in two sub-directories: `atari` containing code for Atari experiments and `gym` containing code for OpenAI Gym experiments.
+See corresponding READMEs in each folder for instructions; scripts should be run from the respective directories.
+It may be necessary to add the respective directories to your PYTHONPATH.
