+# babel-preset-backpack
+
+This package includes the [Babel](https://babeljs.io) preset used by [nodepack](https://github.com/moonreach/nodepack)
+
+## Usage in Nodepack Projects
+
+The easiest way to use this configuration is with Nodepack, which includes it by default. **You don’t need to install it separately in Nodepack projects.**
+
+## Usage Outside of Nodepack
+
+If you want to use this Babel preset in a project not built with Nodepack, you can install it with following steps.
+
+First, [install Babel](https://babeljs.io/docs/setup/).
+
+Then create a file named `.babelrc` with following contents in the root folder of your project:
+
+```js
+{
+  "presets": ["@moonreach/nodepack"]
+}
+```
+
+This preset uses the `useBuiltIns` option with [transform-object-rest-spread](http://babeljs.io/docs/plugins/transform-object-rest-spread/), which assumes that `Object.assign` is available or polyfilled.
