+# (CleanRL) **PPO** Agent Playing **CrazyClimber-v5**
+
+This is a trained model of a PPO agent playing CrazyClimber-v5.
+The model was trained by using [CleanRL](https://github.com/vwxyzjn/cleanrl) and the most up-to-date training code can be
+found [here](https://github.com/vwxyzjn/cleanrl/blob/master/cleanrl/cleanba_impala_envpool_impala_atari_wrapper_a0_l1_d4.py).
+
+## Get Started
+
+To use this model, please install the `cleanrl` package with the following command:
+
+```
+pip install "cleanrl[jax,envpool,atari]"
+python -m cleanrl_utils.enjoy --exp-name cleanba_impala_envpool_impala_atari_wrapper_a0_l1_d4 --env-id CrazyClimber-v5
+```
+
+Please refer to the [documentation](https://docs.cleanrl.dev/get-started/zoo/) for more detail.
+
+
+## Command to reproduce the training
+
+```bash
+curl -OL https://huggingface.co/cleanrl/CrazyClimber-v5-cleanba_impala_envpool_impala_atari_wrapper_a0_l1_d4-seed2/raw/main/cleanba_impala_envpool_impala_atari_wrapper.py
