 To use this package, simply import `schema` from [rivet](https://typst.app/universe/package/rivet) and call `schema.load` to parse a schema description. Then use `schema.render` to render it, et voilà !
 ```typ
 #import "@preview/rivet:0.3.0": schema
-#let doc = schema.load(yaml("path/to/schema.yaml"))
+#let doc = schema.load("path/to/schema.yaml")
 #schema.render(doc)
