```

1\) Build Image with Dockerfile

* `-t` names build, `.` says which files to use
* `-f [DOCKERFILE PATH]` lets you specify Dockerfile

2\) Run It

* it allows `Ctrl-C` to stop it
* `-p 80:4000` means in container runs on port 4000, but you can access at localhost:80
* `-d` runs in detached mode
* `-it` runs in interactive mode so you can kill
* `-v "$(pwd)"/backend:/app` mounts the files at /backend to the docker containers /app allowing instant changes!

*Its possible to use a -v to mount your filesystem to the contianer auto updating on changessss*
