+## Diffusers support
+
+You can also use the checkpoints with the `diffusers` library.
+
+Make sure to install `diffusers` from source:
+
+```bash
+pip install git+https://github.com/huggingface/diffusers
+```
+
+And then install `gguf`:
+
+```bash
+pip install -U gguf
+```
+
+And then we're ready to perform inference:
