+Asynchronously removes a file or symbolic link. No arguments other than a
+possible exception are given to the completion callback.
+
+```js
+// Assuming that 'path/file.txt' is a regular file.
+fs.unlink('path/file.txt', (err) => {
+  if (err) throw err;
+  console.log('path/file.txt was deleted');
+});
+```
+
+`fs.unlink()` will not work on a directory, empty or otherwise. To remove a
+directory, use [`fs.rmdir()`][].
