+[Optimum Habana](https://github.com/huggingface/optimum-habana) is the interface between the Hugging Face Transformers and Diffusers libraries and Habana's Gaudi processor (HPU).
+It provides a set of tools enabling easy and fast model loading, training and inference on single- and multi-HPU settings for different downstream tasks.
+Learn more about how to take advantage of the power of Habana HPUs to train and deploy Transformers and Diffusers models at [hf.co/hardware/habana](https://huggingface.co/hardware/habana).
+
+## Stable Diffusion HPU configuration
+
+This model only contains the `GaudiConfig` file for running **Stable Diffusion v2** (e.g. [stabilityai/stable-diffusion-2-1](https://huggingface.co/stabilityai/stable-diffusion-2-1)) on Habana's Gaudi processors (HPU).
+
+**This model contains no model weights, only a GaudiConfig.**
+
+This enables to specify:
+- `use_habana_mixed_precision`: whether to use Habana Mixed Precision (HMP)
+    - `hmp_opt_level`: optimization level for HMP, see [here](https://docs.habana.ai/en/latest/PyTorch/PyTorch_Mixed_Precision/PT_Mixed_Precision.html#configuration-options) for a detailed explanation
+    - `hmp_bf16_ops`: list of operators that should run in bf16
+    - `hmp_fp32_ops`: list of operators that should run in fp32
+    - `hmp_is_verbose`: verbosity
+
+## Usage
+
+The `GaudiStableDiffusionPipeline` (`GaudiDDIMScheduler`) is instantiated the same way as the `StableDiffusionPipeline` (`DDIMScheduler`) in the 🤗 Diffusers library.
+The only difference is that there are a few new training arguments specific to HPUs.
+
+Here is an example with one prompt:
+```python
+from optimum.habana import GaudiConfig
+from optimum.habana.diffusers import GaudiDDIMScheduler, GaudiStableDiffusionPipeline
+
+
+model_name = "stabilityai/stable-diffusion-2-1"
+
+scheduler = GaudiDDIMScheduler.from_pretrained(model_name, subfolder="scheduler")
+
+pipeline = GaudiStableDiffusionPipeline.from_pretrained(
+    model_name,
+    height=768,
+    width=768,
+    scheduler=scheduler,
+    use_habana=True,
+    use_hpu_graphs=True,
+    gaudi_config="Habana/stable-diffusion-v2",
+)
+
+outputs = generator(
+    ["An image of a squirrel in Picasso style"],
+    num_images_per_prompt=6,
+    batch_size=2,
+)
+```
