 ## Tutorial
 
 Follow our [tutorial](https://getstream.io/chat/angular/tutorial/) and build your first Stream Angular chat application.

-## Mobile application with Ionic
-
-[Ionic](https://ionicframework.com/docs/) is a toolkit for building cross-platform mobile applications from web applications. We have a [minimal chat mobile application](https://github.com/GetStream/ionic-angular-chat-app) using our SDK and Ionic to showcase how you can use the two together (please note that the sample application doesn't have push notifications, and we haven't yet validated that they are working with Ionic, but if you want to try it out our [push notification guide](https://getstream.io/chat/docs/javascript/push_introduction/?language=javascript) can get you started).

+
+This guide shows you how to create a Stream chat mobile app with [Ionic + Capacitor](https://ionicframework.com/docs/). The guide is based on the [Ionic + Angular tutorial](https://ionicframework.com/docs/angular/your-first-app).
+
+You can find the [required tools](https://ionicframework.com/docs/angular/your-first-app#download-required-tools) in the Ionic guide.
+
+## Install ionic tooling
+
+```bash
+npm install -g @ionic/cli native-run cordova-res
+```
+
+## Create the app
+
+Next, create an Ionic Angular app using the "sidemenu" template and add Capacitor for native functionality:
+
+```bash
+ionic start chat-app sidemenu --type=angular --capacitor
+```
+
+Next, change into the app folder:
+
+```bash
+cd chat-app
+```
+
+You can start the app with the following command:
+
+```bash
+npm start
+```
+
+## Create the chat UI
+
+Install the necessary dependencies:
+
+```
+npm install stream-chat-angular stream-chat @ngx-translate/core
+```
+
+Add this to your `tsconfig.json` file to the `compilerOptions` part:
+
+```
+"allowSyntheticDefaultImports": true
+```
+
+Import CSS in your `global.scss` file:
+
+```
+@import "~stream-chat-angular/src/assets/styles/v2/scss/index.scss";
+```
+
+Add the module imports required by `stream-chat-angular` to the `app.module.ts` file:
+
+```typescript
+import { NgModule } from "@angular/core";
+import { BrowserModule } from "@angular/platform-browser";
+import { RouteReuseStrategy } from "@angular/router";
+
+import { IonicModule, IonicRouteStrategy } from "@ionic/angular";
+
+import { AppComponent } from "./app.component";
+import { AppRoutingModule } from "./app-routing.module";
+import { TranslateModule } from "@ngx-translate/core";
+import {
+  StreamAutocompleteTextareaModule,
+  StreamChatModule,
+} from "stream-chat-angular";
+
+@NgModule({
+  declarations: [AppComponent],
+  imports: [
+    BrowserModule,
+    IonicModule.forRoot(),
+    AppRoutingModule,
+    TranslateModule.forRoot(),
+    StreamAutocompleteTextareaModule,
+    StreamChatModule,
+  ],
+  providers: [{ provide: RouteReuseStrategy, useClass: IonicRouteStrategy }],
+  bootstrap: [AppComponent],
+})
+export class AppModule {}
+```
+
+Connect to your Stream chat application by replacing the content of the `app.component.ts` file (add the necessary credentials to your `environment.ts` file):
+
+If you don't already have a Stream account you can [start your free trial](https://getstream.io/try-for-free/).
+
+```typescript
+import { Component, OnInit } from "@angular/core";
+import { environment } from "src/environments/environment";
+import {
+  ChatClientService,
+  ChannelService,
+  StreamI18nService,
+} from "stream-chat-angular";
+
+@Component({
+  selector: "app-root",
+  templateUrl: "./app.component.html",
+  styleUrls: ["./app.component.scss"],
+})
+export class AppComponent implements OnInit {
+  constructor(
+    private chatService: ChatClientService,
+    private channelService: ChannelService,
+    private streamI18nService: StreamI18nService
+  ) {
+    const apiKey = environment.apiKey;
+    const userId = environment.userId;
+    const userToken = environment.userToken;
+    this.chatService.init(apiKey, userId, userToken);
+    this.streamI18nService.setTranslation();
+  }
+
+  async ngOnInit() {
+    this.channelService.init({
+      type: "messaging",
+      members: { $in: [environment.userId] },
+    });
+  }
+}
+```
+
+Display the channel list in your `app.component.html`:
+
+```html
+<ion-app>
+  <ion-split-pane contentId="main-content">
+    <ion-menu contentId="main-content" type="overlay">
+      <ion-content>
+        <ion-menu-toggle auto-hide="false">
+          <ion-list>
+            <stream-channel-list></stream-channel-list>
+          </ion-list>
+        </ion-menu-toggle>
+      </ion-content>
+    </ion-menu>
+    <ion-router-outlet id="main-content"></ion-router-outlet>
+  </ion-split-pane>
+</ion-app>
+```
+
+Extend the `folder.module.ts` with the necessary module imports:
+
+```typescript
+import { NgModule } from "@angular/core";
+import { CommonModule } from "@angular/common";
+import { FormsModule } from "@angular/forms";
+
+import { IonicModule } from "@ionic/angular";
+
+import { FolderPageRoutingModule } from "./folder-routing.module";
+
+import { FolderPage } from "./folder.page";
+import { StreamChatModule } from "stream-chat-angular";
+
+@NgModule({
+  imports: [
+    CommonModule,
+    FormsModule,
+    IonicModule,
+    FolderPageRoutingModule,
+    StreamChatModule,
+  ],
+  declarations: [FolderPage],
+})
+export class FolderPageModule {}
+```
+
+Display the active channel in the `folder.page.html`:
+
+```html
+<ion-content [fullscreen]="true">
+  <stream-channel>
+    <stream-channel-header>
+      <ion-menu-button></ion-menu-button>
+    </stream-channel-header>
+    <stream-message-list></stream-message-list>
+    <stream-notification-list></stream-notification-list>
+    <stream-message-input></stream-message-input>
+    <stream-thread name="thread">
+      <stream-message-list mode="thread"></stream-message-list>
+      <stream-message-input mode="thread"></stream-message-input>
+    </stream-thread>
+  </stream-channel>
+</ion-content>
+```
+
+Our chat UI is now ready.

+
+## Deploying to iOS and Android
+
+Create a clean build
+
+```bash
+ionic build
+```
+
+Next, create both the iOS and Android projects:
+
+```bash
+ionic cap add ios
+ionic cap add android
+```
+
+For more information see the [Ionic guide](https://ionicframework.com/docs/angular/your-first-app/deploying-mobile)
+
+Open the iOS app:
+
+```bash
+ionic cap open ios
+```
+
+This will open XCode on your machine, you can start the app by clicking the play button on the top toolbar.
+
+Open the Android app:
+
+```bash
+ionic cap open android
+```
+
+This will open Android studio on your machine, you can start the app by clicking the play button on the top toolbar.
+
+We've successfully deployed our Stream chat mobile app to iOS and Android.
+
+## Push notifications
+
+We have a separate [push notification guide](./push-guide.mdx) to show you how to add push notifications to your mobile apps.
