+
+DataLoader is a generic utility to be used as part of your Vert.x application's batch data fetching layer to provide a
+consistent API over various back-ends and reduce requests to those back-ends via batching and caching.
+
+The code is a direct port of the [facebook/dataloader](https://github.com/facebook/dataloader) reference
+implementation provided by Facebook, with some slight modifications to make it work for Java 8
+and [Vert.x](http://vertx.io).
+
+Be sure to check the original documentation: https://github.com/facebook/dataloader/blob/master/README.md
