Custom code/resources for indexing Multiple-Images field

Hi, I’m trying to put a gallery from my multiple image field. I know right now it’s only possible with custom code.
It’s my first time using webflow. I’ve been a developer and I have templates from my other sites. But I need some help referencing the multiple-images field from my custom code. Right now I can only reference the field as a whole. Is there some documentation on this?
