Create a Landing Page

[louvis]

Create a landing page to introduce the tools to all users. It should be simple, clean and address the following questions:

• Who's the tool for?
• What can you do with the tool?
• Where did the data come from?

If there is copy/style for me to follow, I might be able to tackle this. I'm not in DC anymore, but if working remote isn't an issue I can take a stab.

@jmithani I started to create a markdown file for this but only got a skeleton so far. If you want to work from it here's what I started.

This data tool is designed for affordable housing advocates and government officials to better understand the state of affordable housing in Washington, DC.

#What can it do?
The tool provides a dyamic view of all affordable housing in the city that can be filtered down to generate targeted insights and analysis.

#Where is the data from?
Data has been gathered from multiple sources including the DC Governement, Urban Institue, HUD, and the US Census Bureau. A full listing of data sources is located [here](http://example.com).
