City guide, architecture and README describe doors and back doors,
door-to-door routes along alleys, and the street furniture on folder
pavements. Documentation screenshots retaken on the current build,
including a street-level view of doorways, a streetlight and routes.
README covers what CodeNavigator is, screenshots of each view, quick
start, configuration, keyboard shortcuts and links to docs/: a city
guide (what every visual means, getting around), architecture (indexer,
sessions, GitHub, rendering passes, routing), the HTTP API, GitHub App
setup including the alert permissions, deployment (Docker, systemd,
nginx, limits, security notes) and development (tests, layout,
conventions, design notes).
