* Setting up 

After reading the following on https://hub.docker.com/r/browserless/chrome

Getting Chrome running well in docker is also a challenge as there's quiet a few packages you need in order to get Chrome running. Once that's done then there's still missing fonts, getting libraries to work with it, and having limitations on service reliability.

Made me think twice about setting it up myself, so just grabbed this for now. 

- I realized soon eough that ws://localhost:3000 is browserless' own API, so I went
  and tried to figure out how to go about getting the websocket for the chrome
  devtools, turns out I need to launch an instance first.

Browserless has an API but I went through the documentation and quickly felt
like it probably defeats the purpose of the exercise to use them, so I instead
used this;

https://hub.docker.com/r/zenika/alpine-chrome

Perhaps the exercise is looking for me to actually build an image from scratch,
but let's make progress on all other other tasks before tackling that.
