+## Getting Started
+
+### Prerequisites
+
+Check your installation of `npm` and `node`:
+
+```sh
+node -v
+npm -v
+```
+
+We strongly recommend using a Node version manager like [nvm](https://github.com/nvm-sh/nvm) (for Mac) or [nvm-windows](https://github.com/coreybutler/nvm-windows) (for Windows) to install Node.js and npm. See [Downloading and installing Node.js and npm](https://docs.npmjs.com/downloading-and-installing-node-js-and-npm).
+
+### Installation
+
+1. Clone the repo & install dependencies

+2. Set up secrets:

+   ```shell
+    npx expo start
+   ```
+2. There are several ways to test the app:
+   - **Expo Go (Recommended)**: [download Expo Go](https://docs.expo.dev/get-started/installation/#2-expo-go-app-for-android-and) on your phone, **connect to same network as your laptop**, and use your phone camera to scan the QR code displayed in the command line.
+   - Web: typing `w` into the expo command line opens the app in a web view.
+     - Warning: since the app is designed to be used on a mobile app, web compatibility might be limited, and some functionality might be different when using the web setup.
