For now it should be any computer that can run a React Native Expo development environment, so most any Windows/Mac/Linux computer plus the relevant Android or iOS device or emulator.

Once we have the codebase to a point where it's worth testing, probably end of next week, we'll add better setup instructions in the README. Most people will want to wait for the test builds via TestFlight and Google Play or raw APKs, ETA 7-10 days on those.

For now if you want to try local setup, check out the Expo environment setup instructions: https://docs.expo.dev/get-started/set-up-your-environment/
