+
+#### The buffer module from [node.js](https://nodejs.org/), for the browser.

+[saucelabs-url]: https://saucelabs.com/u/buffer
+
+With [browserify](http://browserify.org), simply `require('buffer')` or use the `Buffer` global and you will get this module.
+
+The goal is to provide an API that is 100% identical to
+[node's Buffer API](https://nodejs.org/api/buffer.html). Read the
+[official docs](https://nodejs.org/api/buffer.html) for the full list of properties,
+instance methods, and class methods that are supported.
+
+## features
+
+- Manipulate binary data like a boss, in all browsers!
+- Super fast. Backed by Typed Arrays (`Uint8Array`/`ArrayBuffer`, not `Object`)
+- Extremely small bundle size (**6.75KB minified + gzipped**, 51.9KB with comments)
+- Excellent browser support (IE 11, Edge, Chrome, Firefox, Safari 5.1+, Opera, iOS, etc.)
+- Preserves Node API exactly, with one minor difference (see below)
+- Square-bracket `buf[4]` notation works!
+- Does not modify any browser prototypes or put anything on `window`
+- Comprehensive test suite (including all buffer tests from node.js core)
+
+
+## install
+
+To use this module directly (without browserify), install it:
+
+```bash
+npm install buffer
+```
+
+This module was previously called **native-buffer-browserify**, but please use **buffer**
+from now on.
+
+A standalone bundle is available [here](https://wzrd.in/standalone/buffer), for non-browserify users.
+
+
+## usage
+
+The module's API is identical to node's `Buffer` API. Read the
+[official docs](https://nodejs.org/api/buffer.html) for the full list of properties,
+instance methods, and class methods that are supported.
+
+As mentioned above, `require('buffer')` or use the `Buffer` global with
+[browserify](http://browserify.org) and this module will automatically be included
+in your bundle. Almost any npm module will work in the browser, even if it assumes that
+the node `Buffer` API will be available.
+
+To depend on this module explicitly (without browserify), require it like this:
+
+```js
+var Buffer = require('buffer/').Buffer  // note: the trailing slash is important!
+```
+
+To require this module explicitly, use `require('buffer/')` which tells the node.js module
+lookup algorithm (also used by browserify) to use the **npm module** named `buffer`
+instead of the **node.js core** module named `buffer`!
+
+
+## how does it work?
+
+The Buffer constructor returns instances of `Uint8Array` that have their prototype
+changed to `Buffer.prototype`. Furthermore, `Buffer` is a subclass of `Uint8Array`,
+so the returned instances will have all the node `Buffer` methods and the
+`Uint8Array` methods. Square bracket notation works as expected -- it returns a
+single octet.
+
+The `Uint8Array` prototype remains unmodified.
+
+
+## tracking the latest node api
+
+This module tracks the Buffer API in the latest (unstable) version of node.js. The Buffer
+API is considered **stable** in the
+[node stability index](https://nodejs.org/docs/latest/api/documentation.html#documentation_stability_index),
+so it is unlikely that there will ever be breaking changes.
+Nonetheless, when/if the Buffer API changes in node, this module's API will change
+accordingly.
+
+## related packages
+
+- [`buffer-reverse`](https://www.npmjs.com/package/buffer-reverse) - Reverse a buffer
+- [`buffer-xor`](https://www.npmjs.com/package/buffer-xor) - Bitwise xor a buffer
+- [`is-buffer`](https://www.npmjs.com/package/is-buffer) - Determine if an object is a Buffer without including the whole `Buffer` package
+
+## conversion packages
+
+### convert typed array to buffer
+
+Use [`typedarray-to-buffer`](https://www.npmjs.com/package/typedarray-to-buffer) to convert any kind of typed array to a `Buffer`. Does not perform a copy, so it's super fast.
+
+### convert buffer to typed array
+
+`Buffer` is a subclass of `Uint8Array` (which is a typed array). So there is no need to explicitly convert to typed array. Just use the buffer as a `Uint8Array`.
+
+### convert blob to buffer
+
+Use [`blob-to-buffer`](https://www.npmjs.com/package/blob-to-buffer) to convert a `Blob` to a `Buffer`.
+
+### convert buffer to blob
+
+To convert a `Buffer` to a `Blob`, use the `Blob` constructor:
+
+```js
+var blob = new Blob([ buffer ])
+```
+
+Optionally, specify a mimetype:
+
+```js
+var blob = new Blob([ buffer ], { type: 'text/html' })
+```
+
+### convert arraybuffer to buffer
+
+To convert an `ArrayBuffer` to a `Buffer`, use the `Buffer.from` function. Does not perform a copy, so it's super fast.
+
+```js
+var buffer = Buffer.from(arrayBuffer)
+```
+
+### convert buffer to arraybuffer
+
+To convert a `Buffer` to an `ArrayBuffer`, use the `.buffer` property (which is present on all `Uint8Array` objects):
+
+```js
+var arrayBuffer = buffer.buffer.slice(
+  buffer.byteOffset, buffer.byteOffset + buffer.byteLength
+)
+```
+
+Alternatively, use the [`to-arraybuffer`](https://www.npmjs.com/package/to-arraybuffer) module.
+
+## performance
+
+See perf tests in `/perf`.
+
+`BrowserBuffer` is the browser `buffer` module (this repo). `Uint8Array` is included as a
+sanity check (since `BrowserBuffer` uses `Uint8Array` under the hood, `Uint8Array` will
+always be at least a bit faster). Finally, `NodeBuffer` is the node.js buffer module,
+which is included to compare against.
+
+NOTE: Performance has improved since these benchmarks were taken. PR welcoem to update the README.

+
+## Testing the project
+
+First, install the project:
+
+    npm install
+
+Then, to run tests in Node.js, run:
+
+    npm run test-node
+
+To test locally in a browser, you can run:
+
+    npm run test-browser-es5-local # For ES5 browsers that don't support ES6
+    npm run test-browser-es6-local # For ES6 compliant browsers
+
+This will print out a URL that you can then open in a browser to run the tests, using [Zuul](https://github.com/defunctzombie/zuul).
+
+To run automated browser tests using Saucelabs, ensure that your `SAUCE_USERNAME` and `SAUCE_ACCESS_KEY` environment variables are set, then run:
+
+    npm test
+
+This is what's run in Travis, to check against various browsers. The list of browsers is kept in the `.zuul.yml` file.
+
+## JavaScript Standard Style
+
+This module uses [JavaScript Standard Style](https://github.com/feross/standard).
+
+[![JavaScript Style Guide](https://cdn.rawgit.com/feross/standard/master/badge.svg)](https://github.com/feross/standard)
+
+To test that the code conforms to the style, `npm install` and run:
+
+    ./node_modules/.bin/standard
