Fortunately there's an FAQ^h^h^h Story about that: "A GDS Story"

Introduction

The most common questions we’re asked by visitors to GDS are things like:

    “How did it all start in the first place?”
    “How did you get where you are now?”
    “How can I get my government/team/organisation to do similar things?”

This is an attempt to answer those.
