+Run Async
+=========
+
+[![npm](https://badge.fury.io/js/run-async.svg)](http://badge.fury.io/js/run-async) [![tests](https://travis-ci.org/SBoudrias/run-async.svg?branch=master)](http://travis-ci.org/SBoudrias/run-async) [![dependencies](https://david-dm.org/SBoudrias/run-async.svg?theme=shields.io)](https://david-dm.org/SBoudrias/run-async)
+
+Utility method to run a function either synchronously or asynchronously using a series of common patterns. This is useful for library author accepting sync or async functions as parameter. `runAsync` will always run them as an async method, and normalize the multiple signature.
+
+Installation
+=========
+
+```bash
+npm install --save run-async
+```
+
+Usage
+=========
+
+Here's a simple example print the function results and three options a user can provide a function.
+
+```js
+var runAsync = require('run-async');
+
+var printAfter = function (func) {
+  var cb = function (err, returnValue) {
+    console.log(returnValue);
+  };
+  runAsync(func, cb)(/* arguments for func */);
+};
+```
+
+#### Using `this.async`
+```js
+printAfter(function () {
+  var done = this.async();
+
+  setTimeout(function () {
+    done(null, 'done running with callback');
+  }, 10);
+});
+```
+
+#### Returning a promise
+```js
+printAfter(function () {
+  return new Promise(function (resolve, reject) {
+    resolve('done running with promises');
+  });
+});
+```
+
+#### Synchronous function
+```js
+printAfter(function () {
+  return 'done running sync function';
+});
+```
+
+### runAsync.cb
+
+`runAsync.cb` supports all the function types that `runAsync` does and additionally a traditional **callback as the last argument** signature:
+
+```js
+var runAsync = require('run-async');
+
+// IMPORTANT: The wrapped function must have a fixed number of parameters.
+runAsync.cb(function(a, b, cb) {
+  cb(null, a + b);
+}, function(err, result) {
+  console.log(result)
+})(1, 2)
+```
+
+If your version of node support Promises natively (node >= 0.12), `runAsync` will return a promise. Example: `runAsync(func)(arg1, arg2).then(cb)`
