+# MZ - Modernize node.js
+
+[![NPM version][npm-image]][npm-url]
+[![Build status][travis-image]][travis-url]
+[![Test coverage][coveralls-image]][coveralls-url]
+[![Dependency Status][david-image]][david-url]
+[![License][license-image]][license-url]
+[![Downloads][downloads-image]][downloads-url]
+
+Modernize node.js to current ECMAScript specifications!
+node.js will not update their API to ES6+ [for a while](https://github.com/joyent/node/issues/7549).
+This library is a wrapper for various aspects of node.js' API.
+
+## Installation and Usage
+
+Set `mz` as a dependency and install it.
+
+```bash
+npm i mz
+```
+
+Then prefix the relevant `require()`s with `mz/`:
+
+```js
+var fs = require('mz/fs')
+
+fs.exists(__filename).then(function (exists) {
+  if (exists) // do something
+})
+```
+
+With ES2017, this will allow you to use async functions cleanly with node's core API:
+
+```js
+const fs = require('mz/fs')
+
+
+async function doSomething () {
+  if (await fs.exists(__filename)) // do something
+}
+```
+
+## Promisification
+
+Many node methods are converted into promises.
+Any properties that are deprecated or aren't asynchronous will simply be proxied.
+The modules wrapped are:
+
+- `child_process`
+- `crypto`
+- `dns`
+- `fs` (uses `graceful-fs` if available)
+- `readline`
+- `zlib`
+
+```js
+var exec = require('mz/child_process').exec
+
+exec('node --version').then(function (stdout) {
+  console.log(stdout)
+})
+```
+
+## Promise Engine
+
+`mz` uses [`any-promise`](https://github.com/kevinbeaty/any-promise).
+
+## FAQ
+
+### Can I use this in production?
+
+Yes, Node 4.x ships with stable promises support. For older engines,
+you should probably install your own promise implementation and register it with
+`require('any-promise/register')('bluebird')`.
+
+### Will this make my app faster?
+
+Nope, probably slower actually.
+
+### Can I add more features?
+
+Sure.
+Open an issue.
+
+Currently, the plans are to eventually support:
+
+- New APIs in node.js that are not available in older versions of node
+- ECMAScript7 Streams
