+
+> Map over promises concurrently
+
+Useful when you need to run promise-returning & async functions multiple times with different inputs concurrently.
+
+## Install
+
+```
+$ npm install p-map
+```
+
+## Usage
+
+```js
+const pMap = require('p-map');
+const got = require('got');
+
+const sites = [
+	getWebsiteFromUsername('https://sindresorhus'), //=> Promise
+	'https://ava.li',
+	'https://github.com'
+];
+
+(async () => {
+	const mapper = async site => {
+		const {requestUrl} = await got.head(site);
+		return requestUrl;
+	};
+
+ 	const result = await pMap(sites, mapper, {concurrency: 2});
+
+	console.log(result);
+	//=> ['https://sindresorhus.com/', 'https://ava.li/', 'https://github.com/']
+})();
+```
+
+## API
+
+### pMap(input, mapper, options?)
+
+Returns a `Promise` that is fulfilled when all promises in `input` and ones returned from `mapper` are fulfilled, or rejects if any of the promises reject. The fulfilled value is an `Array` of the fulfilled values returned from `mapper` in `input` order.
+
+#### input
+
+Type: `Iterable<Promise | unknown>`
+
+Iterated over concurrently in the `mapper` function.
+
+#### mapper(element, index)
+
+Type: `Function`
+
+Expected to return a `Promise` or value.
+
+#### options
+
+Type: `object`
+
+##### concurrency
+
+Type: `number` (Integer)\
+Default: `Infinity`\
+Minimum: `1`
+
+Number of concurrently pending promises returned by `mapper`.
+
+##### stopOnError
+
+Type: `boolean`\
+Default: `true`
+
+When set to `false`, instead of stopping when a promise rejects, it will wait for all the promises to settle and then reject with an [aggregated error](https://github.com/sindresorhus/aggregate-error) containing all the errors from the rejected promises.
