+
+This is the backend for the RADAR REST Source Authorizer application.
+
+## Sentry monitoring
+
+To enable Sentry monitoring:
+1. Set a `SENTRY_DSN` environment variable that points to the desired Sentry DSN.
+2. (Optional) Set the `SENTRY_LOG_LEVEL` environment variable to control the minimum log level of events sent to Sentry.
+   The default log level for Sentry is `WARN`. Possible values are `TRACE`, `DEBUG`, `INFO`, `WARN`, and `ERROR`.
