+# p-timeout [![Build Status](https://travis-ci.org/sindresorhus/p-timeout.svg?branch=master)](https://travis-ci.org/sindresorhus/p-timeout)
+
+> Timeout a promise after a specified amount of time
+
+
+## Install
+
+```
+$ npm install --save p-timeout
+```
+
+
+## Usage
+
+```js
+const delay = require('delay');
+const pTimeout = require('p-timeout');
+
+const delayedPromise = delay(200);
+
+pTimeout(delayedPromise, 50).then(() => 'foo');
+//=> [TimeoutError: Promise timed out after 50 milliseconds]
+```
+
+
+## API
+
+### pTimeout(input, ms, [message | fallback])
+
+Returns a decorated `input` that times out after `ms` time.
+
+#### input
+
+Type: `Promise`
+
+Promise to decorate.
+
+#### ms
+
+Type: `number`
+
+Milliseconds before timing out.
+
+#### message
+
+Type: `string` `Error`<br>
+Default: `'Promise timed out after 50 milliseconds'`
+
+Specify a custom error message or error.
+
+If you do a custom error, it's recommended to sub-class `pTimeout.TimeoutError`.
+
+#### fallback
+
+Type: `Function`
+
+Do something other than rejecting with an error on timeout.
+
+You could for example retry:
+
+```js
+const delay = require('delay');
+const pTimeout = require('p-timeout');
+
+const delayedPromise = () => delay(200);
+
+pTimeout(delayedPromise(), 50, () => {
+	return pTimeout(delayedPromise(), 300);
+});
+```
+
+### pTimeout.TimeoutError
+
+Exposed for instance checking and sub-classing.
