 Install by cloning this project into your `custom_nodes` folder.
 
-```
+```sh

 ## Quick Start
 
-1. Annotate editable inputs, for example rename the `KSampler` by `KSampler [my sampler]`

+4. You can now run the workflow from the API by doing a `POST /api/workflows/ENDPOINT_NAME` with a json payload like :
 
-`POST /api/workflows/ENDPOINT_NAME`
