+# (CleanRL) **SAC** Agent Playing **Swimmer-v4**
+
+This is a trained model of a SAC agent playing Swimmer-v4.
+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/sac_continuous_action.py).
+
+## Get Started
+
+To use this model, please install the `cleanrl` package with the following command:
+
+```
+pip install "cleanrl[sac_continuous_action]"
+python -m cleanrl_utils.enjoy --exp-name sac_continuous_action --env-id Swimmer-v4
+```
+
+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/sdpkjc/Swimmer-v4-sac_continuous_action-seed5/raw/main/sac_continuous_action.py
+curl -OL https://huggingface.co/sdpkjc/Swimmer-v4-sac_continuous_action-seed5/raw/main/pyproject.toml
