• Doc issue

SUMMARY

There are currently no surfaced dev docs for ansible-navigator. Was working with @thedoubl3j on fixing issue #598 and had some trouble with building source and testing. We would like to start building some dev_docs to step through the process for anyone wanting to get started on developing features or bugfixing navigator issues.

Initial doc suggestions:

• Getting started with developing ansible-navigator - environment set-up with vscode
• Walkthrough/summary of src files
• Overview of base entry points
• Building from src and installing packages for testing
• Testing process and examples

[thedoubl3j]

while there is python docs, particularly around setup.py, surfacing as much info as possible to either the docs dir or even just a general dev guide I think will help out a lot for people either looking to hack a little bit on their own install of navigator or those looking to contribute.
