+For the full configuration options, see [ScaffoldConfigFile](../api/modules#scaffoldconfigfile).
 
 If you want to supply functions inside the configurations, you must use a `.js`/`.cjs`/`.mjs` file
 as JSON does not support non-primitives.
 
-A `.js` file can be just like a `.json` file, make sure to export the final configuration:
-
-```js
-/** @type {import('simple-scaffold').ScaffoldConfigFile} */
-module.exports = {
-  component: {
-    templates: ["templates/component"],
-    output: "src/components",
-  },
-}
-```
-
 Another feature of using a JS file is you can export a function which will be loaded with the CMD
 config provided to Simple Scaffold. The `extra` key contains any values not consumed by built-in
 flags, so you can pre-process your args before outputting a config:

 ## Use In Node.js
 
 You can also start a scaffold from Node.js with a remote file or URL config.
