 Running the model can be done through the notebooks provided in the [inference](inference) section. You will find more 
 details regarding downloading the models, compute requirements as well as some tutorials on how to use the models. 
 Specifically, there are four notebooks provided for the following use-cases:
-#### Text-to-Image

 We also provide our own implementation for training and using LoRAs with Stable Cascade, which can be used to finetune 
 the text-conditional model (Stage C). Specifically, you can add and learn new tokens and add LoRA layers to the model.

 Lastly, one thing that might be very interesting for people, especially if you want to train your own text-conditional
 model from scratch, maybe even with a completely different architecture than our Stage C, is to use the (Diffusion) 
 Autoencoder that Stable Cascade uses to be able to work in the highly compressed space. Just like people use Stable
