evanpelle ac63315449 Move contributing docs to CONTRIBUTING.md and require approved issues
Consolidate the contribution workflow, governance, and translation
sections from README.md into CONTRIBUTING.md, leaving the README with a
single pointer.

Document the new process: contributors must work from issues labelled
`approved` (or open one and wait for the label), comment to be assigned,
and link the issue from their PR. PRs without an approved issue will be
auto-closed (except small bug fixes), and PRs that appear AI-generated
without genuine author understanding will be closed.

[OpenFront.io](https://openfront.io/) is an online real-time strategy game focused on territorial control and alliance building. Players compete to expand their territory, build structures, and form strategic alliances in various maps based on real-world geography.
This is a fork/rewrite of WarFront.io. Credit to https://github.com/WarFrontIO.

## 🌟 Features
- **Real-time Strategy Gameplay**: Expand your territory and engage in strategic battles
- **Alliance System**: Form alliances with other players for mutual defense
- **Multiple Maps**: Play across various geographical regions including Europe, Asia, Africa, and more
- **Resource Management**: Balance your expansion with defensive capabilities
- **Cross-platform**: Play in any modern web browser
## 📋 Prerequisites
- [npm](https://www.npmjs.com/) (v10.9.2 or higher)
- A modern web browser (Chrome, Firefox, Edge, etc.)
## 🚀 Installation
1. **Clone the repository**
```bash
git clone https://github.com/openfrontio/OpenFrontIO.git
cd OpenFrontIO
```
2. **Install dependencies**
```bash
npm run inst
```
Do NOT use `npm install` nor `npm i` but instead use our `npm run inst`. It runs the safer `npm ci --ignore-scripts` to install dependencies exactly according to the versions in `package-lock.json` and doesn't run scripts. This can prevent being hit by a supply chain attack.
## 🎮 Running the Game
### Development Mode
Run both the client and server in development mode with live reloading:
```bash
npm run dev
```
This will:
- Start the webpack dev server for the client
- Launch the game server with development settings
- Open the game in your default browser (to disable this behavior, set `SKIP_BROWSER_OPEN=true` in your environment)
### Client Only
To run just the client with hot reloading:
```bash
npm run start:client
```
### Server Only
To run just the server with development settings:
```bash
npm run start:server-dev
```
### Connecting to staging or production backends
Sometimes it's useful to connect to production servers when replaying a game, testing user profiles, purchases, or login flow.
> To replay a production game, make sure you're on the same commit that the game you want to replay was executed on, you can find the `gitCommit` value via `https://api.openfront.io/game/[gameId]`.
> Unfinished games cannot be replayed on localhost.
To connect to staging api servers:
```bash
npm run dev:staging
```
To connect to production api servers:
```bash
npm run dev:prod
```
## 🛠️ Development Tools
- **Format code**:
```bash
npm run format
```
- **Lint code**:
```bash
npm run lint
```
- **Lint and fix code**:
```bash
npm run lint:fix
```
- **Testing**
```bash
npm test
```
