Complete the full Developer Guide so it is ready for general use about examples

[TheMosquito]

After an intro about "what is Edge" (and why is it like this), I think this sort of table of contents:

• Develop Code
  • Docker Linux containers
  • Use any recent Linux distribution,
  • Use any programming language and libraries,
• Setup Horizon Edge
  • Tools provided to simplify code signing
  • Tools provided to simulate Horizon Edge deployment for development testing
  • Deploy (to a registry -- public and private registries supported)
  • Publish to the Horizon Exchange
  • Define software "Deployment Patterns" for your Edge machines
• Continuously Deploy
  • Easily automate your development cycle right out to Edge machines, if you wish
• Register Machines
  • Install and configure the Horizon Edge software
  • Specify its Deployment Pattern
• Horizon Software Components
  • Horizon Exchange
  • Edge software:
    • Horizon Agent ("anax")
    • Horizon Agreement Bot ("agbot")
• Edge Software Design
  • Hardware architectures
  • Microservices, modularity
  • Software size
  • Software dependencies (self-contained)
  • Software configuration, customization
  • Privilege, access
  • CPU/GPU/memory consumption
  • Network bandwidth
  • Network outage-tolerant

Thoughts?

As today comes to a close I have completed the first part of the above outline. The most interesting, and hopefully the easiest to write, portions remain:

1. How Horizon Works

• Overview
• Horizon Exchange
• Horizon Switchboard
• Horizon Agent ("anax")
• Horizon Agreement Bot ("agbot")

1. Edge Software Design

• Hardware architectures
• Microservices, modularity
• Software size
• Software dependencies (self-contained)
• Software configuration, customization
• Privilege, access
• CPU/GPU/memory consumption
• Network bandwidth
• Network outage-tolerant
  I have not made any diagrams at all yet. So it's just a long text file at this point. I plan to go back and add diagrams when the text is all done. I think the first draft can be published without the diagrams and just add them as they are created.
  So far it's about 20K of text (around 3000 words).
