Getting started


I have an idea for a project which I think Graphhopper can help me with, but whilst I’ve got some experience with writing code, I could use some help getting started with Graphhopper (and, Github, as it happens).

What I want to do is:

Take a set of starting points and a list of destinations, each generated using Overpass and then calculate the (walking) distance between each start point and each end point.

Can anyone point me in the right direction with the second half of this? Starting with the fundamentals - if I write some java code to do this, where do I run it? Do I need to install Graphhopper somewhere? I’m using Linux (Ubuntu)
