+# p-limit [![Build Status](https://travis-ci.org/sindresorhus/p-limit.svg?branch=master)](https://travis-ci.org/sindresorhus/p-limit)
+
+> Run multiple promise-returning & async functions with limited concurrency
+
+
+## Install
+
+```
+$ npm install --save p-limit
+```
+
+
+## Usage
+
+```js
+const pLimit = require('p-limit');
+
+const limit = pLimit(1);
+
+const input = [
+	limit(() => fetchSomething('foo')),
+	limit(() => fetchSomething('bar')),
+	limit(() => doSomething())
+];
+
+// only one promise is run at once
+Promise.all(input).then(result => {
+	console.log(result);
+});
+```
+
+
+## API
+
+### pLimit(concurrency)
+
+Returns a `limit` function.
