### Open in browser

Using a modern browser that supports WebRTC, like a recent version of Chrome or Firefox, open several windows of [http://localhost:12345](http://localhost:12345).
Copy your user ID from one client to the peer ID input on another client to establish a connection between the two.

## 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.
