Nice! Definitely a point of confusion for people so having something
like this to reference and point to the more detailed areas is great.
What’s your vision for this article? A doc repo? A wiki? Wikis def
make it more likely to get updated.

Not sure if this doc is the best place but I’d like to see a best practices on
file format (i.e. use .json) and runtime config file locations (i.e. /etc/ /var type
decisions). Also, the recommendation to make your data runtime config
vs. build time config when possible (to make live debug/test easier).
