+This demo was tested on an Intel Mac on 2023 April 01 with Capacitor 4.7.3 and
+`@capacitor/filesystem` 4.1.4
 
-Follow the [React Native demo](#demo) to ensure iOS and Android sims are ready.
+The iOS simulator runs iOS 16.2 on an iPhone 14 Pro Max.
 
+The Android simulator runs Android 12.0 (S) API 31 on a Pixel 3.

+### Base Project
+
+1) Disable telemetry.
+
+```bash
+npx @capacitor/cli telemetry off
+```
+
+Verify that telemetry is disabled by running
+
+```bash
+npx @capacitor/cli telemetry
+```
+
+(it should print `Telemetry is off`)

+4) Create CapacitorJS structure:
 
 ```bash

+
+5) Download [`src/App.svelte`](pathname:///cap/App.svelte) and replace:
+
+```bash
+curl -o src/App.svelte -L https://docs.sheetjs.com/cap/App.svelte
+```
+
+### iOS
+
+6) Follow the [React Native demo](/docs/demos/mobile/reactnative#demo) to
+ensure the iOS simulator is ready.
+
+7) Create iOS app
+
+```bash
+npm i --save @capacitor/ios
 npx cap add ios
 ```
 
-4) Replace the contents of `src/App.svelte` with the following:
+8) Enable file sharing and make the documents folder visible in the iOS app.
+The following lines must be added to `ios/App/App/Info.plist`:

+(The root element of the document is `plist` and it contains one `dict` child)
+
+9) Run the app in the simulator
 
 ```bash
-npm run build; npx cap sync; npx cap run ios
+npm run build
+npx cap sync
+npx cap run ios
 ```
 
-There are 3 steps: build the Svelte app, sync with CapacitorJS, and run sim.
-This sequence must be run every time to ensure changes are propagated.
+10) Test the app
 
-</details>
+Open the app and observe that presidents are listed in the table.
+
+Touch "Export XLSX" and a popup will be displayed.
+
+To see the generated file, switch to the "Files" app in the simulator and look
+for `SheetJSCap.xlsx` in "On My iPhone" > "`sheetjs-cap`"
+
+### Android
+
+11) Follow the [React Native demo](/docs/demos/mobile/reactnative#demo) to
+ensure the Android simulator is ready.
+
+12) Create Android app
+
+```bash
+npm i --save @capacitor/android
+npx cap add android
+```
+
+13) Enable file reading and writing in the Android app.
+The following lines must be added to `android/app/src/main/AndroidManifest.xml`

+
+14) Run the app in the simulator
+
+```bash

+npx cap sync
+npx cap run android
+```
+
+15) Test the app
+
+Open the app and observe that presidents are listed in the table.
+
+Touch "Export XLSX" and the emulator will ask for permission:
+
+Tap "Allow" and a popup will be displayed with a path.
+
+To see the generated file, switch to the "Files" app in the simulator, tap the
+`≡` icon and tap "Documents". Tap "Documents" folder to find `SheetJSCap.xlsx`.
