I usually use a wrangle to get height map and apply it to the geo. But you can use an AttributeFromMap node and a Peak node to do the same thing too.
You can scale the height attribute before applying it, like the third window.
no tutorial needed, just connect the SDF to the height port of the preview material. you can use flow blocks, noises, shapes, or any other nodes as the first input.
