 > Compile ES2015 default and rest parameters to ES5
 
-This plugin transforms ES2015 parameters to ES5, this includes:
+See our website [@babel/plugin-transform-parameters](https://new.babeljs.io/docs/en/next/babel-plugin-transform-parameters.html) for more information.
 
-- Destructuring parameters
-- Default parameters
-- Rest parameters
+## Install
 
-## Examples
-
-**In**
-
-```javascript
-function test(x = "hello", { a, b }, ...args) {
-  console.log(x, a, b, args);
-}
-```
-
-**Out**
-
-```javascript
-function test() {
-  var x = arguments.length > 0 && arguments[0] !== undefined ? arguments[0] : "hello";
-  var _ref = arguments[1];
-  var a = _ref.a,
-      b = _ref.b;
-
-  for (var _len = arguments.length, args = Array(_len > 2 ? _len - 2 : 0), _key = 2; _key < _len; _key++) {
-    args[_key - 2] = arguments[_key];
-  }
-
-  console.log(x, a, b, args);
-}
-```
-
-## Installation
+Using npm:
 
 ```sh
-npm install --save-dev @babel/plugin-transform-parameters
+npm install --save @babel/plugin-transform-parameters
 ```
 
-## Caveats
-
-Default parameters desugar into `let` declarations to retain proper semantics. If this is
-not supported in your environment then you'll need the
-[@babel/plugin-transform-block-scoping](http://babeljs.io/docs/plugins/transform-block-scoping) plugin.
-
-## Usage
-
-### Via `.babelrc` (Recommended)
-
-**.babelrc**
-
-```json
-{
-  "plugins": ["@babel/plugin-transform-parameters"]
-}
-```
-
-### Via CLI
+or using yarn:
 
 ```sh
-babel --plugins @babel/plugin-transform-parameters script.js
-```
-
-### Via Node API
-
-```javascript
-require("@babel/core").transform("code", {
-  plugins: ["@babel/plugin-transform-parameters"]
-});
-```
-
-## Options
-
-### `loose`
-
-`boolean`, defaults to `false`.
-
-In loose mode, parameters with default values will be counted into the arity of the function. This is not spec behavior where these parameters do not add to function arity.
-
-The `loose` implementation is a more performant solution as JavaScript engines will fully optimize a function that doesn't reference `arguments`. Please do your own benchmarking and determine if this option is the right fit for your application.
-
-```javascript
-// Spec behavior
-function bar1 (arg1 = 1) {}
-bar1.length // 0
-
-// Loose mode
-function bar1 (arg1 = 1) {}
-bar1.length // 1
+yarn add --save @babel/plugin-transform-parameters
