# R4D4RVU — fully offline ADS-B radar from your own RTL-SDR dongle.
#
#   1. Plug in your RTL-SDR dongle.
#   2. Copy .env.example to .env and set your receiver LAT / LON (and TZ).
#   3. docker compose up -d
#   4. Open  http://localhost:8078/   (it launches straight into SDR mode)
#
# Two services:
#   readsb  — decodes ADS-B from the dongle and serves /data/aircraft.json on :8080
#   radar   — nginx that serves R4D4RVU and proxies /data/ to readsb (same-origin,
#             so the browser can read the feed with no CORS / mixed-content issues)
