# Contribution Guide

## Setup

1. Install Node.js 20+.
2. Run `npm install`.
3. Run `npm run dev`.
4. Run `npm run docker-up` to verify the single-container path.

## Expectations

- Keep client gameplay code under `client/src/game`.
- Keep API and persistence code under `server/src`.
- Keep production assumptions aligned with the single-container deployment model.
- Prefer small milestone-focused changesets.

## CI Baseline

The repo includes a first-pass workflow that runs install, lint, test, build, and Docker build checks on pushes and pull requests.
