+This project is a React port of the jQuery-based [PivotTable.js](https://pivottable.js.org/) (by the same author) and is under active development, but it's early days and not production-ready yet.
+
+## Project Goals
+
+* Similar API to PivotTable.js but more uniform
+* ES6 instead of CoffeeScript
+* React instead of jQuery
+* Plotly.js instead of C3.js
+
+## Roadmap to Release
+
+* See [Issue #1](https://github.com/plotly/react-pivottable/issues/1)
