Docker development environment

[Coolomina]

Hello!,

What about having a Docker development environment so we don't have to install all the dependencies in our local machine?, I can do the PR myself 😄

Thanks!

Maybe something like this??

In a docker-compose.yml:

version: '2.4'

services:
  jekyll:
    image: bretfisher/jekyll-serve
    volumes:
      - .:/site
    ports:
      - '80:4000'
