Add infra blog post to site

[tosteiner]

@dannycolin soo, I was thinking... if I wanted to add the infrastructure post to the blog roll, how would this work?

Just add the md-file to https://github.com/OpenScienceMOOC/site/tree/master/_posts , and that's it? And where can I put media files?
Thanks in advance!

(just thinking aloud here: maybe we can also pull Lisa's post in as per #47 ? cc @Protohedgehog )

Create a new markdown file in _posts following this naming convention

YYYY-MM-DD-your-post-title.md

After that, add the following metadata at the top of your post:

---
title: "Your Post Title"
author: "Your Name"
date: "YYYY-MM-DD"
layout: post
categories: cat1 cat2
---

Now for the images, create a folder posts inside /assets/img/ and put your images in it. You should now be able to link to your image in your markdown file like so:

![Image description](/assets/img/posts/your-image.ext)

Don't hesitation to ping me on Slack if something doesn't work ;)
