 ### Angular
 
-#### Config Provider
+#### Config
 
 The `Config.set()` method has been removed. See https://ionicframework.com/docs/angular/config for examples on how to set config globally, per-component, and per-platform.
 
+Additionally, the `setupConfig` function is no longer exported from `@ionic/angular`. Developers should use `IonicModule.forRoot` to set the config instead. See https://ionicframework.com/docs/angular/config for more information.
+
+### React
+
+#### Config
+
+All Ionic React applications must now import `setupIonicReact` from `@ionic/react` and call it. If you are setting a custom config with `setupConfig`, pass your config directly to `setupIonicReact` instead:
+
+**Old**
+```javascript
+import { setupConfig } from '@ionic/react';
+
+setupConfig({
+  mode: 'md'
+})
+```
+
+**New**
+```javascript
+import { setupIonicReact } from '@ionic/react';
+
+setupIonicReact({
+  mode: 'md'
+})
+```
+
+Note that all Ionic React applications must call `setupIonicReact` even if they are not setting custom configuration.
+
+Additionally, the `setupConfig` function is no longer exported from `@ionic/react`.
 
 ### Vue
 
+#### Config
+
+The `setupConfig` function is no longer exported from `@ionic/vue`. Developers should pass their config into the `IonicVue` plugin. See https://ionicframework.com/docs/vue/config for more information.
+
 #### Tabs Config
 
 Support for child routes nested inside of tabs has been removed to better conform to Vue Router's best practices. Additional routes should be written as sibling routes with the parent tab as the path prefix:
