A section or block definition comes with a list of settings. Those settings will be used by the editor UI to render the proper content form of a section (or block).
For instance, if your section includes 2 settings, let's say a title (text) and a background image (image), then the editor UI will generate for this section a form with 2 input elements: a text input for the input and an image picker to select the background image.
