Docker Information

	#### Run within Docker
	For now we have to build the docker image locally. Late I will get it hosted
	###### Building your image
	Go to the directory that has your Dockerfile and run the following command to build a Docker image. The -t flag lets you tag your image so it’s easier to find later using the docker images command:

	`docker build -t hamiltondanielb/record-web-react .`

	Your image will now be listed by Docker:

	`docker images`
