Instructions for Mac:

First things first run:

npm install

To launch the app run:

npm start

This will launch the app on localhost:3000

Docker

I've also added a Dockerfile so you can run the app in docker.

Install Docker first - i think you can go here https://store.docker.com/search?offering=community&q=&type=edition

Then run:

docker build -t .

and then:

docker run -p :3000

where is the port you want to run the app on - localhost:

Once you have got it running in docker if you want to kill it, open a new terminal window:

docker ps

gives you a list of running docker images, and then taking the NAMES (last column) from the previous command

docker kill
