 #### With create-react-app Projects
+
 If you created your project with `create-react-app` you'll have some extra work to do, or you wont have syntax highlighting. Using the webpack plugin requires updating your webpack config, which `create-react-app` abstracts away. You can `npm eject` your project, but you may not want to do that. To keep your app set up in the `create-react-app` style but to get access to your webpack config you can use `react-app-rewired`.
 
 First, install `react-app-rewired` as a development dependency:
+
 ```sh
 $ npm install -D react-app-rewired
 ```
 
 Next, replace all of the `react-script` references in your `package.json` `scripts` section with `react-app-required`:
+
 ```json
  "scripts": {
     "start": "react-app-rewired start",

-Next, create a `config-overrides.js` file at the root of your project and add the following:
-
-```javascript
-const MonacoWebpackPlugin = require('monaco-editor-webpack-plugin');
-
-module.exports = function override(config, env) {  
-    config.plugins.push(new MonacoWebpackPlugin({
-        languages: ['json', 'yaml', 'shell']
-    }));
-    return config;
-}
-```
-
-Note: You should change the `languages` array based on your needs. 
-
 You can now start your app with `npm start` and syntax highlighting should work.
 
 #### Enable YAML Syntax Highlighting

+Finally, to allow the `monaco-yaml` autocomplete to function properly with `@monaco-editor/react`, you should configure your YAML schema in a `beforeMount` call with the `monaco-yaml` `configureMonacoYaml` function. This `beforeMount` function should be passed to `CodeEditor` via the `editorProps` property like so:
+
+```
+editorProps: {
+  beforeMount: yourBeforeMountHandler
+}

 The `monaco-yaml` plugin has a lot of options so check out their docs to see what else you may want to add.
