 Node.js module to list all files in a directory or any subdirectories.
 
 ## Installation
 
+This package is [ESM only](https://gist.github.com/sindresorhus/a39789f98801d908bbc7ff3ecc99d99c): Node 12+ is needed to use it and it must be `import` instead of `require`.
+
 ```bash
 npm install recursive-readdir-files
 ```
 
 ## Usage
 
 ```js
-const recursiveReaddirFiles = require("recursive-readdir-files");
+import recursiveReaddirFiles from 'recursive-readdir-files';
 
 recursiveReaddirFiles(process.cwd(), {
   ignored: /\/(node_modules|\.git)/
