 > JavaScript implementation of the "accept" attribute for HTML5 `<input type="file">`
 
 [![npm](https://img.shields.io/npm/v/attr-accept.svg?style=flat-square)](https://www.npmjs.com/package/attr-accept)
-![Tests](https://img.shields.io/github/actions/workflow/status/react-dropzone/attr-accept/test.yml?branch=master&style=flat-square&label=tests)
+![Tests](https://img.shields.io/github/actions/workflow/status/react-dropzone/attr-accept/test.yml?branch=main&style=flat-square&label=tests)
 
 See https://developer.mozilla.org/en-US/docs/Web/HTML/Element/input/file#attr-accept for more information.
 
+Ships as both ES modules and CommonJS with bundled TypeScript type definitions.
+
 ## Installation
 ```sh
 npm install --save attr-accept
 ```
 
 ## Usage
 ```javascript
-var accept = require('attr-accept');
+import accept from "attr-accept";
+
 accept({
-    name: 'my file.png',
-    type: 'image/png'
-}, 'image/*') // => true
+  name: "my file.png",
+  type: "image/png"
+}, "image/*"); // => true
 
 accept({
-    name: 'my file.json',
-    type: 'application/json'
-}, 'image/*') // => false
+  name: "my file.json",
+  type: "application/json"
+}, "image/*"); // => false
 
 accept({
-    name: 'my file.srt',
-    type: ''
-}, '.srt') // => true
+  name: "my file.srt",
+  type: ""
+}, ".srt"); // => true
 ```
 
 You can also pass multiple mime types as a comma delimited string or array.
 ```javascript
 accept({
-    name: 'my file.json',
-    type: 'application/json'
-}, 'application/json,video/*') // => true
+  name: "my file.json",
+  type: "application/json"
+}, "application/json,video/*"); // => true
 
 accept({
-    name: 'my file.json',
-    type: 'application/json'
-}, ['application/json', 'video/*']) // => true
+  name: "my file.json",
+  type: "application/json"
+}, ["application/json", "video/*"]); // => true
+```
+
+In a CommonJS environment, use `require` instead:
+```javascript
+const accept = require("attr-accept");
 ```
