+
+To set up a Stable Diffusion model is super easy.
+In your models folder make a file called ``stablediffusion.yaml``, then edit that file with the following. (You can change ``Linaqruf/animagine-xl`` with what ever ``sd-lx`` model you would like.
+```yaml
+name: animagine-xl
+parameters:
+  model: Linaqruf/animagine-xl
+backend: diffusers
+
+# Force CPU usage - set to true for GPU
+f16: false
+diffusers:
+  pipeline_type: StableDiffusionXLPipeline
+  cuda: false # Enable for GPU usage (CUDA)
+  scheduler_type: dpm_2_a
+```
+
+If you are using docker, you will need to run in the localai folder with the ``docker-compose.yaml`` file in it
+```bash
+docker-compose down #windows
+docker compose down #linux/mac
+```
+
+Then in your ``.env`` file uncomment this line.
+```yaml
+COMPEL=0
+```
+
+After that we can reinstall the LocalAI docker VM by running in the localai folder with the ``docker-compose.yaml`` file in it
+```bash
+docker-compose up #windows
+docker compose up #linux/mac
+```
+
+Then to download and setup the model, Just send in a normal ``OpenAI`` request! LocalAI will do the rest!
+```bash
+curl http://localhost:8080/v1/images/generations -H "Content-Type: application/json" -d '{
+  "prompt": "Two Boxes, 1blue, 1red",
+  "size": "256x256"
+}'
+```
