6.1.2 Page Content
A study page is an X-expression representing a complete page of HTML content.
Any definition of a study step must be a function that produces an x-expression (or another study, but we won’t go into that here). But you should never need to create these values directly; rather, you’ll typically use helper functions like md and html that do this for you.

6.1.2.3 Static Resources
| (require conscript/resource) | package: conscript |
This module provides a way to access images and other static files that aren’t stored in the database. The files get uploaded automatically as long as they’re linked using define-static-resource. Or you can upload a zipped folder as long as the study is contained/provided from specifically named "study.rkt" inside that zip file.
syntax
(define-static-resource name path-string)
Use this in a "study.rkt" file and make path-string a path that is relative to that file. Then bundle the referenced files into a zip file before uploading to the Congame server. See How to add images for more details.
