 Approaches that help RL performance IID often do not transfer to OOD, even by small distribution shifts. As RL algorithms are inherently learning with non-stationary targets and typically deployed with sim2real transfer, we believe that evaluating OOD is far more valuable to the research community.

 ## Installation 
 
+The following instructions assume you have `conda` installed. 
+If you do not have `conda`, you can install it from [Miniconda](https://docs.conda.io/en/latest/miniconda.html).
+
 
 
+```bash
+cd /path/to/your/clone/of/procgen-ood 
+conda create -n procgen_ood -f environment.yml
+conda activate procgen_ood
+pip install -e .  # install the package in editable mode 
+``` 
 
+Verify the installation by running the following command:
+
+```bash 
+python -m procgen.interactive --env-name coinrun 
+```
