[docs] step 1 rewritten - everything should be highlighted too

This is the 0.1 of the first draft of the Getting Started with Hoodie guide. A lot of it is from http://blog.abcedmindedness.com/2014/03/getting-started-with-hoodie.html, with permission of course, and I hope that I can go through it and flesh it out a lot, using the basic steps as a base.

The first step has been rewritten in a more passive way, and I hope to set the tone and style of the rest of the steps, of which I'll try and do at least one or two a night for the rest of the week, and have a completed first draft for comment and so on. I will also work on a Markdown style guide that I would invite comment on, as having a single location that we can collaborate on and come to some kind of agreement on how to write. I think I've set out the basis for it here, but the more I go through each step I might think that there is a better way of doing such and such.

Hopefully this is the start of many guides popping up, and I'd love to do one for Digital Ocean, and how to deploy hoodie on one of their droplets, as that's how I'm currently playing with Hoodie, and it's pretty easy. So with any luck the whole Hoodie team can use this guide as a basis for introducing people to Hoodie over time, when we have been through a few iterations of it.

I've gone on too long already in this PR, and I'm going to bed now, so hopefully we can have some conversations about this tomorrow. See you in #hoodie-docs. :+1:
