Create an overview doc of infrastructure

I want to create an "overview" type doc in the Infrastructure repo that is basically a one stop overview of all of our infrastructure, onboarding process, and so forth. This should not be very complicated, but would be a great place to point candidates and new hires to show how everything is set up and what kind of things they will be working with. Below is a very rough outline.

• Infrastructure mission statement (who we are and whatnot)
• Infrastructure overview (servers, layout, maybe a graphic)
• What technologies do we use
• What accounts will a new hire need specifically for infrastructure (link to onboarding checklist here perhaps)
• and more?!

@ahanselka what's the status of this?

Er, nothing has happened on it yet. Various fires and a nice bit of time off prevented progress. I'll come up with something today 🙂

Alrighty, I created !6 to add this doc. Suggestions encouraged 😄
