| # Introduction |
| |
| Bluebird is a fully featured promise library with focus on innovative features and performance |
| |
| See the [**bluebird website**](http://bluebirdjs.com/docs/getting-started.html) for further documentation, references and instructions. See the [**API reference**](http://bluebirdjs.com/docs/api-reference.html) here. |
| |
| For bluebird 2.x documentation and files, see the [2.x tree](https://github.com/petkaantonov/bluebird/tree/2.x). |
| |
| ### Note |
| |
| Promises in Node.js 10 are significantly faster than before. Bluebird still includes a lot of features like cancellation, iteration methods and warnings that native promises don't. If you are using Bluebird for performance rather than for those - please consider giving native promises a shot and running the benchmarks yourself. |
