You need to run both the game server (Colyseus-based) and the client application (CRA-based).

---

To run the server:

1. create a .env file at the top level and add values for the following keys:
   LIVEKIT_API_KEY=<YOUR_API_KEY>
LIVEKIT_API_SECRET=<YOUR_API_SECRET>
LIVEKIT_URL=wss://your-livekit-server-url

Note: You can also run a LiveKit instance locally (see: https://github.com/livekit/livekit-server). This guide will help you quickly get started with generating keys. If you run locally, the value for LIVEKIT_URL above would be ws://localhost:7880 by default.

2. yarn; yarn start (at the top level)

---

To run the client:

1. cd client

2. create a .env (or .env.local if running locally) file at the top level and add values for the following keys: REACT_APP_SERVER_URL=https://url-to-the-game-server-above

Note: If you run the game server locally, use http://localhost:2567 as the value for REACT_APP_SERVER_URL

3. yarn; yarn start

In a browser, visit localhost:3000 and you should be placed into a space automatically. Open up multiple browser windows to test pairing with other users or install ngrok and send a link to a friend.
