 Startup times can be approximately 6x slower than without named imports from the top-level API.

 use:
 
 ```js
+// 🚀 Fast
 import Button from '@material-ui/core/Button';
 import TextField from '@material-ui/core/TextField';
 ```
 
+This is the option we document in **all** the demos as the one that requires no configuration. Head to [Option 2](#option-2) for the option we recommend.
+
 While importing directly in this manner doesn't use the exports in [`@material-ui/core/index.js`](https://github.com/mui-org/material-ui/blob/master/packages/material-ui/src/index.js), this file can serve as a handy reference as to which modules are public.
 
 Be aware that we only support first and second level imports. Anything below is considered
 private and can cause module duplication in your bundle.
 
 ```js
-// OK
+// ✅ OK
 import { Add as AddIcon } from '@material-ui/icons';
 import { Tabs } from '@material-ui/core';
 //                                 ^^^^ 1st or top-level

 ```
 
 ### Option 2
 
-**Important note**: This is only supported for `@material-ui/icons`.
-We recommend this approach if you often restart your development build.
+We **recommend** this option as providing the best DX and UX.
+However, you need to apply the following steps correctly.
 
-Another option is to keep using named imports, but still have shorter
-start up times by using `babel` plugins.
+#### 1. Configure Babel
 
 Pick one of the following plugins:
 
 - [babel-plugin-import](https://github.com/ant-design/babel-plugin-import) with the following configuration:
+
   ```js
-  [
-    'babel-plugin-import',
-    {
-      libraryName: '@material-ui/icons',
-      libraryDirectory: 'esm', // or '' if your bundler does not support ES modules
-      camel2DashComponentName: false,
-    },
-  ];
+  plugins: [
+    [
+      'babel-plugin-import',
+      {
+        libraryName: '@material-ui/core',
+        libraryDirectory: 'esm', // or '' if your bundler does not support ES modules
+        camel2DashComponentName: false,
+      },
+      'core',
+    ],
+    [
+      'babel-plugin-import',
+      {
+        libraryName: '@material-ui/icons',
+        libraryDirectory: 'esm', // or '' if your bundler does not support ES modules
+        camel2DashComponentName: false,
+      },
+      'icons',
+    ],
+  ],
   ```
-- [babel-plugin-transform-imports](https://www.npmjs.com/package/babel-plugin-transform-import) has a different api than `babel-plugin-import` but does same thing.
+- [babel-plugin-transform-imports](https://www.npmjs.com/package/babel-plugin-transform-imports) with the following configuration:
+
   ```js
-  [
-    'transform-imports',
+  plugins: [
+    'babel-plugin-transform-imports',
     {
+      '@material-ui/core': {
+        transform: '@material-ui/core/esm/${member}',
+        // for bundlers not supporting ES modules use:
+        // transform: '@material-ui/core/${member}',
+        preventFullImport: true,
+      },
       '@material-ui/icons': {
         transform: '@material-ui/icons/esm/${member}',
         // for bundlers not supporting ES modules use:
         // transform: '@material-ui/icons/${member}',
+        preventFullImport: true,
       },
     },
-  ];
+  ],
   ```
 
+#### 2. Convert all your imports
+
+Finally, you can convert your exisiting codebase to this option with our [top-level-imports](https://github.com/mui-org/material-ui/blob/master/packages/material-ui-codemod/README.md#top-level-imports) codemod.
+It will perform the following diffs:
+
+```diff
+-import Button from '@material-ui/core/Button';
+-import TextField from '@material-ui/core/TextField';
++import { Button, TextField } from '@material-ui/core';
+```
+
 ## ECMAScript
 
 The package published on npm is **transpiled**, with [Babel](https://github.com/babel/babel), to take into account the [supported platforms](/getting-started/supported-platforms/).
