## Set up
### Fetch submodules
```
> git submodule update --init
```
### Install
```
> npm install
```
### Build
```
> npm run build
```
### Run the server
```
> npm start
```
### Open in browser
Using a modern browser that supports WebRTC, like a recent version of Chrome or Firefox, open several windows of [http://localhost:3000](http://localhost:3000).
They will &ndash; for now &ndash; automatically connect with each other using the server for signalling.
## Development
### Precommit Checks
The project is supplied with a `.pre-commit-config.yml`. This file defines the checks that [pre-commit](https://pre-commit.com/) must execute on every `git commit`.
To use pre-commit (RECOMMENDED):
1. Install it, following the instructions available at the link provided;
2. Hook it to the project, by running `pre-commit install` from the project's root directory.
Whenever a pre-commit check fails, it fixes the code in place for you and aborts the commit.
You therefore have to `git add .` and reissue the `git commit` command.
