+# babel-plugin-object-set-prototype-of-to-assign
+
+
+The `object-set-prototype-of-to-assign` plugin will transform all `Object.setPrototypeOf` calls to a method that will do a shallow defaults of all properties.
+
+**NOTE:** There are some caveats when using this plugin, see the [`babel-plugin-proto-to-assign` README](https://github.com/babel-plugins/babel-plugin-proto-to-assign) for more information..
+
+## Example
+
+**In**
+
+```javascript
+Object.setPrototypeOf(bar, foo);
+```
+
+**Out**
+
+```javascript
+var _defaults = ...;
+
+_defaults(bar, foo);
+```
+
+## Installation
+
+```sh
+$ npm install babel-plugin-object-set-prototype-of-to-assign
+```
+
+## Usage
+
+### Via `.babelrc` (Recommended)
+
+**.babelrc**
+
+```json
+{
+  "plugins": ["object-set-prototype-of-to-assign"]
+}
+```
+
+### Via CLI
+
+```sh
+$ babel --plugins object-set-prototype-of-to-assign script.js
