 ### _Notes for Running on M1 Mac:_
 
 The app currently only builds for x86_64 simulators. Simulators prior to IOS 13.7 are x86_64 by default, however starting with 13.7 they become platform specific. In order to get an x86_64 simulator of a newer IOS version, one must set XCode to open in [emulation using Rosetta](https://www.macworld.com/article/338843/how-to-force-a-native-m1-mac-app-to-run-as-an-intel-app-instead.html). To run the project, open [GaloyApp.xcworkspace](./ios/GaloyApp.xcworkspace/) in XCode, choose an x86_64 simulator, and click the play button. This should start the Metro bundler in a new terminal as well as launch the simulator with the app.

+# Development Environment
+Developing the Blink  Mobile app for the Galoy Backend can be done in a variety of ways but the officially supported method is via [Nix Flake](../flake.nix) at the root of the repository.
+
+## Prerequisites
+
+Before you start, ensure you have the following installed on your system:
+
+- [Nix (set up with Flakes)](https://github.com/DeterminateSystems/nix-installer) - Make sure you have flake support turned on
+- [Direnv](https://direnv.net) - Hooked up to your shell
+- [Docker](https://docs.docker.com/get-docker/) - Optional, only if you need the backend locally
+
+Detailed setup process of individual components is documented in our central repository [here](https://github.com/GaloyMoney/galoy/blob/main/docs/DEVELOPMENT_ENVIRONMENT.md).
+
+## Project Setup
+
+Once Nix and direnv are set up, follow these steps to set up the galoy-mobile project:
+
+1. **Clone the Repository**: Clone the galoy-mobile repository to your local machine using Git.
+
+   ```bash
+   git clone git@github.com:GaloyMoney/galoy-mobile.git
+   cd galoy-mobile
+   ```
+
+1. **Allow Direnv to run it's contents**:
+
+   ```bash
+   direnv allow
+   ```
+
+   This would download all of the dependencies needed to work with the Galoy Mobile. 
+   This step sets up the NodeJS runtime, Android SDKs and creates the Emulator AVD for you in it's own separate chamber.
+   It also builds Ruby which is needed for some dependencies.
+   If you're on a Mac, it also lets you know if you're on an unsupported XCode version and gives you instructions on how to switch to a supported one.
+
+1. **Install Node and Cocoapods(macOS) Dependencies**
+
+   ```bash
+   yarn install
+   ```
+
+### Android Development
+
+To run the application on Android:
+
+1. **Start the Metro Development Server**:
+
+   - Run `yarn start` in one terminal window. If `yarn start` fails on the first run, restart the command as it's a known issue.
+
+1. **Start the Emulator**:
+   - Run `make emulator` in one terminal. This starts the Android emulator. You can also BYOE (bring your own emulator) and run it from your Android Studio.
+
+1. **Run the Application**:
+   - In another terminal, run `yarn android`. If you encounter "error Failed to launch emulator," it's expected and won't exit the android build. Our emulator device will still be available to the Android Debug Bridge (adb).
+
+If while running the app on the emulator, `yarn start` crashes, then just restart it and rerun the application.

+```
+
+</details>
+
+### iOS Development (Mac Only)
+
+To run the application on iOS:
+
+1. **Xcode and Simulator Setup**:
+   - Make sure you have Xcode (and preferably on a version that direnv didn't complain to you about). If you don't you can download it using the `xcodes` CLI [see step](#xcode-and-simulator-setup-using-xcodes).
+   - Make sure you have an XCode Simulator Runtime. You probably have it if you had XCode installed previously but you can verify it by running `open -a simulator`. If it fails, you probably don't have it and you can download it using `xcodes` as well [see step](#xcode-and-simulator-setup-using-xcodes).
+
+1. **Start the Metro Development Server**:
+
+   - Run `yarn start` in one terminal window.
+
+1. **Run the Application**:
+   - Run `yarn ios` to start the application on iOS.

+
+##### XCode and Simulator Setup using xcodes
+
+You can download XCode and Simulator blazingly fast and let the CLI do all of the set up for you hassle free.
+Here are the commands that do it:
+
+```bash
+xcodes install 15.3 # Or whatever version direnv tells you about
+xcodes runtimes install "iOS 17.4" # Or the latest iOS out there
+```
+
+Xcodes install for the first time prompts you for Apple ID and Password. This is because Apple's license for XCode prohibits distribution of XCode from other servers than their own. And downloads from it can only work if you are authenticated. Hence, to use XCode, you need an Apple ID.
