+# p-is-promise [![Build Status](https://travis-ci.org/sindresorhus/p-is-promise.svg?branch=master)](https://travis-ci.org/sindresorhus/p-is-promise)
+
+> Check if something is a promise
+
+Why not [`is-promise`](https://github.com/then/is-promise)? That module [checks for a thenable](https://github.com/then/is-promise/issues/6), not an ES2015 promise. This one is stricter.
+
+You most likely don't need this. Just pass your value to `Promise.resolve()` and let it handle it.
+
+Can be useful if you need to create a fast path for a synchronous operation.
+
+
+## Install
+
+```
+$ npm install p-is-promise
+```
+
+
+## Usage
+
+```js
+const pIsPromise = require('p-is-promise');
+const Bluebird = require('bluebird');
+
+pIsPromise(Promise.resolve('🦄'));
+//=> true
+
+pIsPromise(Bluebird.resolve('🦄'));
+//=> true
+
+pIsPromise('🦄');
+//=> false
+```
