## Changes made
- Fleshed out main top-level README file
- Added formal docs for code of conduct and security (that just lead to
the Coder Docs)
- Revamped contributing guide
- Added a few images to help support the new docs
## Notes
- Just because we're not supporting templates for the moment, I did
deliberately limit the number of mentions to it.
Closes https://github.com/coder/internal/issues/531
## Changes made
- Added functionality to validate the structure of module README files (frontmatter and the README body)
- Added a really basic snapshot-ish test for the module README body validation
- Updated README files that were previously violating README requirements (the old modules validation logic wasn't catching these)
- Changed `ValidationPhase` from an int to a string
