+
+An ES7/ES2016 spec-compliant `Array.prototype.includes` shim/polyfill/replacement that works as far down as ES3.
+
+This package implements the [es-shim API](https://github.com/es-shims/api) interface. It works in an ES3-supported environment and complies with the proposed [spec](https://262.ecma-international.org/6.0/).
+
+Because `Array.prototype.includes` depends on a receiver (the `this` value), the main export takes the array to operate on as the first argument.
+
+Engines that need this package include:
+ - IE (all versions)
+ - Safari < 9
+ - Firefox < 43, and 99-101
+ - Chrome < 47
+ - Edge < 14
+ - node < 6
+
+## Getting started
+
+```sh
+npm install --save array-includes
+```
+
+## Usage
+
+Basic usage: **includes(array, value[, fromIndex=0])**
+
+```js
+var includes = require('array-includes');
+var assert = require('assert');
+var arr = [ 'one', 'two' ];
+
+includes(arr, 'one'); // true
+includes(arr, 'three'); // false
+includes(arr, 'one', 1); // false
+```
+
+
+
+## Example
+
+```js
+var arr = [
+	1,
+	'foo',
+	NaN,
+	-0
+];
+
+assert.equal(arr.indexOf(0) > -1, true);
+assert.equal(arr.indexOf(-0) > -1, true);
+assert.equal(includes(arr, 0), true);
+assert.equal(includes(arr, -0), true);
+
+assert.equal(arr.indexOf(NaN) > -1, false);
+assert.equal(includes(arr, NaN), true);
+
+assert.equal(includes(arr, 'foo', 0), true);
+assert.equal(includes(arr, 'foo', 1), true);
+assert.equal(includes(arr, 'foo', 2), false);
+```
+
+```js
+/* when Array#includes is not present */
+delete Array.prototype.includes;
+var shimmedIncludes = includes.shim();
+
+assert.equal(shimmedIncludes, includes.getPolyfill());
+assert.equal(arr.includes('foo', 1), includes(arr, 'foo', 1));
+```
+
+```js
+/* when Array#includes is present */
+var shimmedIncludes = includes.shim();
+
+assert.equal(shimmedIncludes, Array.prototype.includes);
+assert.equal(arr.includes(1, 'foo'), includes(arr, 1, 'foo'));
+```
+
+## Tests
