Context

Juno currently lacks a streamlined way of onboarding new developers, both in understanding the project conceptually and specific documentation for Juno's services. This ticket aims to significantly improve the developer's experience via a refactoring of much of the Juno's documentation.

Tasks

• Fix Juno README instructions mentioning nonexistent docker compose (it's now split)
• Add READMEs for all Juno services (instead of the default nest)
• Collect all of the existing diagrams we have of Juno and modify/add as needed--this will help with streamlining the onboarding process
• Keep a main overview of how each repository relates to another, as we're currently lacking a bit on this end
