-## Example
+See our website [@babel/plugin-proposal-decorators](https://new.babeljs.io/docs/en/next/babel-plugin-proposal-decorators.html) for more information.
 
-(examples are from proposal)
+## Install
 
-### Simple class decorator
+Using npm:
 
-```js
-@annotation
-class MyClass { }
-
-function annotation(target) {
-   target.annotated = true;
-}
-```
-
-### Class decorator
-
-```js
-@isTestable(true)
-class MyClass { }
-
-function isTestable(value) {
-   return function decorator(target) {
-      target.isTestable = value;
-   }
-}
-```
-
-### Class function decorator
-
-```js
-class C {
-  @enumerable(false)
-  method() { }
-}
-
-function enumerable(value) {
-  return function (target, key, descriptor) {
-     descriptor.enumerable = value;
-     return descriptor;
-  }
-}
-```
-
-## Installation
-
 ```sh
-npm install --save-dev @babel/plugin-proposal-decorators
+npm install --save @babel/plugin-proposal-decorators
 ```
 
-## Usage
+or using yarn:
 
-Add the following line to your .babelrc file:
-
-```json
-{
-  "plugins": ["@babel/plugin-proposal-decorators"]
-}
-```
-
-### Via CLI
-
 ```sh
-babel --plugins @babel/plugin-proposal-decorators script.js
+yarn add --save @babel/plugin-proposal-decorators
 ```
-
-### Via Node API
-
-```javascript
-require("@babel/core").transform("code", {
-  plugins: ["@babel/plugin-proposal-decorators"]
-});
-```
-
-## Options
-
-### `legacy`
-
-`boolean`, defaults to `false`.
-
-Use the legacy (stage 1) decorators syntax and behavior.
-
-#### NOTE: Compatibility with `@babel/plugin-proposal-class-properties`
-
-If you are including your plugins manually and using `@babel/plugin-proposal-class-properties`, make sure that `@babel/plugin-proposal-decorators` comes *before* `@babel/plugin-proposal-class-properties`.
-
-When using the `legacy: true` mode, `@babel/plugin-proposal-class-properties` must be used in `loose` mode to support the `@babel/plugin-proposal-decorators`.
-
-Wrong:
-
-```json
-{
-  "plugins": [
-    "@babel/plugin-proposal-class-properties",
-    "@babel/plugin-proposal-decorators"
-  ]
-}
-```
-
-Right:
-
-```json
-{
-  "plugins": [
-    "@babel/plugin-proposal-decorators",
-    "@babel/plugin-proposal-class-properties"
-  ]
-}
-```
-
-```json
-{
-  "plugins": [
-    ["@babel/plugin-proposal-decorators", { "legacy": true }],
-    ["@babel/plugin-proposal-class-properties", { "loose" : true }]
-  ]
-}
-```
