+### HF Diffusers load AutoencoderKL (VAE)
 
 Loads a VAE directly. Generally speaking, the pipeline loads its own VAE, but
 you can use this to use a custom VAE, or to, e.g., load the VAE on a different
 device than the rest of the pipeline.
 
-## HF Transformers load model
+### HF Transformers load model
 
 Load a HuggingFace *Transformers* (not Diffusers) model. Generally for the text
 encoder. The pipeline loads its own text encoder, but you can use this to use a
 custom encoder or load it on a different device, etc.
