[WIP] - Arranger Dev Documentation

[MitchellShiell]

The branch is linked and rendered on a single, easy-to-navigate developer hub that beautifully renders all our product documentation from the /docs folder of all our GitHub repositories.

• [ ] An updated Readme.md file.
• [x] A /docs folder with the following basic structure:

.
├── /overview
└── /setup

Usage will be added next (but not included in this round of review)

• [x] An updated contributing file
• [x] An updated code_of_conduct file
• [x] An updated license.md file

To Review

• [ ] Overview page
  • I require input filling in the descriptions for the repository structure section
• [ ] Setup page
• [ ] Readme
