+## Training using 🤗 `trl`
+
+🤗 `trl` provides a [`DDPOTrainer` class](https://huggingface.co/docs/trl/ddpo_trainer) which lets you fine-tune Stable Diffusion on different reward functions using DDPO. The integration supports LoRA, too.  You can check out the [supplementary blog post](https://huggingface.co/blog/trl-ddpo) for additional guidance. The DDPO integration was contributed by @metric-space to `trl`.
