+
+> Reduce a list of values using promises into a promise for a value
+
+Useful when you need to calculate some accumulated value based on async resources.
+
+
+## Install
+
+```
+$ npm install --save p-reduce
+```
+
+
+## Usage
+
+```js
+const pReduce = require('p-reduce');
+const humanInfo = require('human-info'); // not a real module
+
+const names = [
+	getUser('sindresorhus').then(info => info.name),
+	'Addy Osmani',
+	'Pascal Hartig',
+	'Stephen Sawchuk'
+];
+
+pReduce(names, (total, name) => {
+	return humanInfo(name).then(info => total + info.age);
+}, 0).then(totalAge => {
+	console.log(totalAge);
+	//=> 125
+});
+```
+
+
+## API
+
+### pReduce(input, reducer, [initialValue])
+
+Returns a `Promise` that is fulfilled when all promises in `input` and ones returned from `reducer` are fulfilled, or rejects if any of the promises reject. The fulfilled value is the result of the reduction.
+
+#### input
+
+Type: `Iterable<Promise|any>`
+
+Iterated over serially in the `reducer` function.
+
+#### reducer(previousValue, currentValue, index)
+
+Type: `Function`
+
+Expected to return a value. If a `Promise` is returned, it's awaited before continuing with the next iteration.
+
+#### initialValue
+
+Type: `any`
+
+Value to use as `previousValue` in the first `reducer` invocation.
