+# d3
+
+This branch contains the prerelease of D3 4.0. This API is unstable and may change at any point prior to the release!
+
+…
+
+## Installing
+
+If you use NPM, `npm install d3`. Otherwise, download the [latest release](https://github.com/mbostock/d3/releases/latest). The released bundle supports AMD, CommonJS, and vanilla environments. Create a custom build using [Rollup](https://github.com/rollup/rollup) or your preferred bundler. You can also load directly from [d3js.org](https://d3js.org):
