+# Contributing
+
+We welcome code contributions, feature requests, and reporting of issues. Please
+see [guidelines and instructions](.github/CONTRIBUTING.md).
+
+---
+
+This repo is subdivided into 3 parts using pnpm workspaces:
+
+- The base repo (workspace name = `checkout-sheet-kit-react-native`)
+- The `@shopify/checkout-sheet-kit` Native Module (workspace name = `module`)
+- The sample application (workspace name = `sample`)
+
+Each of the workspaces contains a separate `package.json` to manage tasks
+specific to each workspace.
+
+## Getting started
+
+If you've cloned the repo and want to run the sample app, you will first need to:
+
+1. Install the NPM dependencies
+
+   ```sh
+   pnpm install
+   ```
+
+2. Install iOS dependencies. (N.b. Android dependencies are automatically installed by Gradle)
+
+   ```sh
+   pnpm pod-install sample/ios
+   ```
+
+3. Build the Native Module
+
+   ```sh
+   pnpm module build
+   ```
+
+4. Start the Metro server
+
+   ```sh
+   pnpm sample start
+   ```
+
+5. Run the sample application (in a new terminal / tab)
+
+   ```sh
+   pnpm sample ios
+   # or
+   pnpm sample android
+   ```
+
+## Optional: Speed up builds with sccache
+
+For faster native compilation (especially on incremental builds), you can install [sccache](https://github.com/mozilla/sccache), a shared compilation cache:
+
+```sh
+# macOS (using Homebrew)
+brew install sccache
+
+# Ubuntu/Debian
+cargo install sccache
+
+# Other systems: see https://github.com/mozilla/sccache#installation
+```
+
+The build scripts will automatically detect and use sccache if available. On Android, React Native's CMake files look for a command named `ccache`, so the sample Android scripts put an sccache-backed compatibility command first on `PATH`. If you encounter any build issues, you can temporarily disable it:
+
+```sh
+# Disable sccache for a single build
+SCCACHE=false pnpm sample ios
+SCCACHE=false pnpm sample android
+```
+
+## Making changes to the Native Module
+
+If your intentions are to modify the TS code for the Native Module under
+`modules/@shopify/checkout-sheet-kit`, note that you will not need to rebuild to
+observe your changes in the sample app. This is because the sample app is
+importing the TS files directly from the module directory (through symlinking).
+
+However, if you're running the iOS/Android tests against the module, you will
+first need to run `pnpm module build` each time you change the TS code.
+
+## Cleaning the workspaces
+
+There are a handful of commands to clean the individual workspaces.
+
+```sh
+# Clear the current directory from watchman
+pnpm clean
+
+# Removes the "sample/node_modules" directory
+# Removes "ios/pods" directory
+# Removes "ios/build" directory
+pnpm sample clean
+
+# Removes the "lib" directory for the Native Module
+pnpm module clean
+```
+
+## Linting the code
+
+Linting the codespaces will (1) compile the code with TypeScript and (2) run
+eslint over the source code.
+
+```sh
+# Lint the Native Module TS code
+pnpm module lint
+
+# Lint the Sample App TS code
+pnpm sample lint
+```
+
+## Testing
+
+There are 3 types of tests in this repo: Typescript, Swift and Java - each for
+testing the Native Module.
+
+```sh
+# Run Jest tests for "modules/@shopify/checkout-sheet-kit/src/**/*.tsx"
+pnpm test
+
+# Run swift tests for the Native Module
+pnpm sample test:ios
+
+# Run Java tests for the Native Module
+pnpm sample test:android
+```
+
+## Running the sample app
+
+To run the sample app in this repo, first clone the repo and run the following
+commands at the root of the project directory.
+
+### Install NPM dependencies
+
+```sh
+pnpm install
+```
+
+### Install Cocoapods
+
+```sh
+pnpm pod-install sample/ios
+```
+
+### Build the local module
+
+```sh
+pnpm module build
+```
+
+### Update the dotenv file
+
+Replace the details in the `sample/.env.example` file and rename it to
+`sample/.env`
+
+```
+# Storefront Details
+STOREFRONT_DOMAIN="YOUR_STORE.myshopify.com"
+STOREFRONT_ACCESS_TOKEN="YOUR_PUBLIC_STOREFRONT_ACCESS_TOKEN"
+STOREFRONT_VERSION="2025-07"
+```
+
+### Start the sample app
+
+```sh
+pnpm sample start
+```
