+## InvenTree App Development
+
+For developers looking to contribute to the project, we use Flutter for app development. The project has been tested in Android Studio (on both Windows and Mac) and also VSCode.
+
+## Prerequisites
+
+To build the app from source, you will need the following tools installed on your system:
+
+- Android Studio or Visual Studio Code (with Flutter and Dart plugins)
+- [Flutter Version Management (FVM)](https://fvm.app/) - We use FVM to manage Flutter versions
+
+### iOS Development
+
+For iOS development, you will need a Mac system with XCode installed.
+
+### Java Version
+
+Some versions of Android Studio ship with a built-in version of the Java JDK. However, the InvenTree app requires [JDK 17](https://www.oracle.com/java/technologies/javase/jdk17-archive-downloads.html) to be installed.
+
+If you see any errors related to JDK version mismatch, download and install the correct version of the JDK (from the link above) and update your Android Studio settings to point to the correct JDK location:
+
+```bash
+fvm flutter config --jdk-dir /path/to/jdk
+```
+
+## Invoke Tasks
+
+We use the [invoke](https://www.pyinvoke.org) to run some core tasks - you will need python and invoke installed on your local system.
+
+## Flutter Version Management (FVM)
+
+This project uses [Flutter Version Management (FVM)](https://fvm.app/) to ensure consistent Flutter versions across development environments and CI/CD pipelines.
+
+For installation instructions, please refer to the [official FVM documentation](https://fvm.app/documentation/getting-started/installation).
+
+Once installed, FVM will automatically use the Flutter version specified in the `.fvmrc` file at the root of the project.
+
+### Visual Studio Code
+
+To set up Visual Studio Code, you will need to make sure the `.vscode` directory exists. Then run `fvm use` to ensure the correct Flutter version is used.
+
+```
+mkdir -p .vscode
+fvm use
+```
+
+#### What happens:
+- Downloads SDK if not cached
+- Creates `.fvm` directory with SDK symlink
+- Updates `.fvmrc` configuration
+- Configures IDE settings
+- Runs `flutter pub get`
+
+
+### Android Studio
+
+To set up Android Studio, run `fvm use` to ensure the correct Flutter version is used.
+
+```
+fvm use
+```
+
+#### What happens:
+- Downloads SDK if not cached
+- Creates `.fvm` directory with SDK symlink
+- Updates `.fvmrc` configuration
+- Runs `flutter pub get`
+
+Set Flutter SDK path in Android Studio:
+
+1. Open Android Studio
+2. Go to `File` -> `Settings` -> `Languages & Frameworks` -> `Flutter`
+3. Set `Flutter SDK path` to `.fvm/flutter_sdk`:
+
+![Setting Flutter SDK path in Android Studio](docs/android_studio_fvm.png)
+
+
+## Getting Started
+
+Initial project setup (after you have installed all required dev tools) is as follows:
+
+Generate initial translation files:
+
+```
+invoke translate
+```
+
+Install required flutter packages:
+```
+fvm flutter pub get
+```
+
+You should now be ready to debug on a connected or emulated device!
+
+## Troubleshooting
+
+### Flutter Doctor
+
+If you're experiencing issues with the development environment, run Flutter Doctor to diagnose problems:
+
+```bash
+fvm flutter doctor -v
+```
+
+This will check your Flutter installation and identify any issues with your setup. Common issues include:
+
+- Missing Android SDK components
+- iOS development tools not properly configured
+- Missing dependencies
+
+Fix any identified issues before proceeding with development.
+
+
+## Building Release Versions
+
+Building release versions for target platforms (either android or iOS) is simplified using invoke:
+
+### Android
+
+Build Android release:
+
+```
+invoke android
+```
+
+### iOS
+
+Build iOS release:
+
+```
+invoke ios
+```

+# Contributing to InvenTree App
+
+Thank you for considering contributing to the InvenTree App! This document outlines some guidelines to ensure smooth collaboration.
+
+## Code Style and Formatting
+
+### Dart Formatting
+
+We enforce consistent code formatting using Dart's built-in formatter. Before submitting a pull request:
+
+1. Run the formatter on your code:
+   ```bash
+   fvm dart format .
+   ```
+
+2. Our CI pipeline will verify that all code follows the standard Flutter/Dart formatting rules. Pull requests with improper formatting will fail CI checks.
+
+### General Guidelines
+
+- Write clear, readable, and maintainable code
+- Include comments where necessary
+- Follow Flutter/Dart best practices
+- Write tests for new features when applicable
+
+## Pull Request Process
+
+1. Fork the repository and create a feature branch
+2. Make your changes
+3. Ensure your code passes all tests and linting
+4. Format your code using `invoke format`
+5. Submit a pull request with a clear description of the changes
+6. Address any review comments
+
+## Development Setup
+
+1. Ensure you have Flutter installed (we use Flutter Version Management)
+2. Check the required Flutter version in the `.fvmrc` file
+3. Install dependencies with `fvm flutter pub get`
+4. Run tests with `fvm flutter test`
+
+## Reporting Issues
+
+When reporting issues, please include:
+- Clear steps to reproduce the issue
+- Expected behavior
+- Actual behavior
+- Screenshots if applicable
+- Device/environment information
+
+Thank you for contributing to the InvenTree App!

+
+**Translation Source File** - app_en.arb
+
+This file contains the source strings for translating. If you want to add a new translatable string to the app, is must be added to this file!
+
+**Translated Files** - <lc>/app_<lb>arb
+
+Each directory contains a single translation output file, generated by the [crowdin translation service](https://crowdin.com/project/inventree). *Do not edit these files*
+
+**collected** - Collected files
+
+Before building the app, the translation files are collected from the various directories into a single directory, so they can be accessed by the app.
+
+### Translating
+
+DO NOT EDIT THE TRANSLATION FILES DIRECTLY!
+
+Translation files are crowd sourced using the [crowdin service](https://crowdin.com/project/inventree). Contributions are welcomed (and encouraged!)
