@igooch @markmandel I think this is ready to be merged into main; would you review and let me know if there are more changes you would want to see? Thanks in advance!

Once again I'd like to affirm that this is a resource worth sharing with the general multiplayer game dev community because it's the highest quality resource I've found when upleveling my understanding of the subject. I keep imagining a fellow curious game developer finding this resource through the Agones open source project and thinking that's a special moment. Hopefully you've had time to review the resource and agree with my assessment!

Looking forward to hearing back soon on this PR.
