The server is not running.

I've followed the steps in the Readme file to start the application, but I got the following:

========================================
  Your Yarn packages are out of date!
  Please run `yarn install --check-files` to update.
========================================


To disable this check, please change `check_yarn_integrity`
to `false` in your webpacker config file (config/webpacker.yml).

After that, I've removed the node_modules folder and run yarn install and then I was able to run the server. Could you please check this?

Is this repo using Yarn or just NPM?
