+> [!NOTE]
+> For iOS, you will first need to [request the HCE entitlement](https://developer.apple.com/contact/request/hce-entitlement/) for using ISO7816 AID `D2760000850101` (i.e. NFC Forum Type 4 Tag - NDEF) before you can run this app.
 
 ## Prerequisites
 1. Clone the repository.
-2. Run `yarn` to install dependencies.
-3. (iOS) Make sure to set up your Signing Team and Bundle Identifier in "Signing & Capabilities" settings section of the project.
-4. (iOS) Ensure that Host Card Emulation (HCE) entitlement is added to the project with proper ISO7816 AIDs enabled.
+2. Run `yarn` inside the project's directory to install dependencies.
+3. (iOS) Install Pods: `cd ios/ && bundle install && bundle exec pod install`. Then, open the project in XCode through the `ios/<project name>.xcworkspace` file.

 While both session and exclusive NFC access are active, you will receive `readerDetected` events even when the HCE emulation is not started at the time (without any explicit UI being displayed by the system). You can then make a call to `startHCE` to initiate the interaction automatically, without needing the user to click anything beforehand.
