How to connect sdb to a running instance of Unity

[cobaltplay]

Hey all. I'm researching into a building a custom debugger for Unity3D.
From what I've read so far it looks like sdb is the way to go.
I've cloned and built the soft debugger from the repo here, however I'm a bit stuck on how to connect it to a running instance of Unity. can someone point me in the right direction?

Thanks for any help :)
