+Node's ESM specifier resolution does not support all default behavior of
+the CommonJS loader. One of the behavior differences is automatic resolution
+of file extensions and the ability to import directories that have an index
+file.
+
+Use this loader to enable automatic extension resolution and importing from
+directories that include an index file, like this:
+
+```js
+import file from './file'; // Where ./file is ./file.js or ./file.mjs
+import index from './folder'; // Where ./folder is ./folder/index.js or ./folder/index.mjs
+```
+
+This loader also applies these automatic resolution rules to the program entry point passed to `node` on the command line:
+
+```console
+$ node index.mjs
+success!
+$ node index # Failure!
+Error: Cannot find module
+$ node --loader=./loader.js index
+success!
+```
