I did a bit of reorganization of this page, which had a bunch of different subjects all stuck together under "Remarks". It was also inconsistent about its use of and , so I tried to remedy that. I think the stuff about topologizing the fundamental groupoid is kind of confusing right now, but I don't know exactly what it's trying to say so I can't fix it.
I have added to the References-section at fundamental groupoid pointers to
The fundamental groupoid as a terminal costack (arXiv:1406.4419)
The Étale Fundamental Groupoid as a Terminal Costack (arXiv:1412.5473)
This observes that for good topological spaces and for Noetherian schemes the fundamental groupoid assignment $\Pi_1(-)$ is characterized as being 2-terminal among all co-stacks.
Cross-linked with simplicial fundamental groupoid.
