Installation is done in a few simple steps and only takes a couple of minutes to get running.
It is highly recommended that you use git to install instead of downloading an archive.
The only requirement is that you have node and npm installed (v6 or newer).
Note for Debian/Ubuntu users: You might need to install the nodejs-legacy package.
Inside the OS.js directory:
$ npm install
$ node osjs build
$ node osjs run
For more information, see the Installation Manual.
