 This implementation of optimization does not require any modification to original Stable Diffusion code.
 
+#### What option to use?
+If you have 4GB VRAM and want to make 512x512 (or maybe up to 640x640) images, use `--medvram`.
+
+If you have 4GB VRAM and want to make images larger than that, use `--lowvram`.
+
+If you have more VRAM and want to make larger images than you can usually make, use `--medvram`. You can use `--lowvram`
+also but the effect will likely be barely noticeable.
+
+Otherwise, do not use any.

 ### Inpainting
 In img2img tab, draw a mask over a part of image, and that part will be in-painted.
