# Set up the hub

## Requirements

You need a computer that runs the Hub.

The application is rather lightweight, so there are no special requirements here
and it could run other applications in parallel. The Hub has a web interface for
monitoring and configuration that can be shown on any browser that can connect to
the computer.

To keep latency to a minimum it would be perfect if this computer uses a wired
connection.

## Setup

The hub requires [node.js](https://nodejs.org/en/) to run. Packages for Linux, MacOS and even Windows
are offered on the [Download page](https://nodejs.org/en/download/). We support the latest LTS version,
which should be `{{ hub_nodejs_version }}` at the moment.

Open the terminal of your operating system, enter the `hub` directory and run

````bash
npm run start
````

Point your browser to the IP of your computer on port {{ hub_default_port }}, for instance http://127.0.0.1:{{ hub_default_port }} if
you are on the same machine. You should see a screen similar to this

Select `Configuration` in the navigation and configure the settings for your Video Mixer.

!!! info
    The Tallies, their assigned channels and your configuration are automatically saved in `.wifi-tally.json`
    in your home directory. So the configuration is restored when the Hub is restarted. 

## Conclusion

When done, go to the next step to [set up a Web Tally](setup-web-tally.md).
