+Note these three important pieces of the page entry:
+
+* `kind: page` - indicates that we are creating a page
+* `path:` - specifies what the name of the page will be in the generated docs.
+  For example, `path: some_funcs` in the config above produces a file called
+  `some_funcs.qmd` in the API reference folder.
+* `contents:` - lists out the contents of the page.
