+# ECMAScript Modules
+For now, ESLint does not support ES Modules. If your project uses ES Modules, these files will need to be renamed from `*.js` to `*.cjs` so that they still operate in CommonJS style within an ES Modules project. However, `parserOptions.sourceType` will still need to be set to `'module'` so that the linter allows `import` and `export` statements.
