Is there any documentation on plugin code lifecycle

[gitcommitshow]

Summary

I didn't find any documentation on plugin lifecycle. As in how plugin code is executed?
Specifically, I'm interested in the order that different parts(gatsby-node, gatsby-ssr, gatsby-browser, index) get executed and how they depend on each other.

If it's not there,
Some recommended topics to cover:

• A flow diagram of how plugin code executed

Motivation

Going through the gatsby code to know plugin code execution lifecycle will take significant time and I believe everyone will be able to develop a bug-free plugin with this documentation.
