+### Environment Variables
+
+The application can be configured using the following environment variables:
+
+- **ALLOWED_HOSTS**: Comma-separated list of allowed hostnames (default: "gitingest.com, *.gitingest.com, localhost, 127.0.0.1")
+- **GITINGEST_METRICS_ENABLED**: Enable Prometheus metrics server (set to any value to enable)
+- **GITINGEST_METRICS_HOST**: Host for the metrics server (default: "127.0.0.1")
+- **GITINGEST_METRICS_PORT**: Port for the metrics server (default: "9090")
+- **GITINGEST_SENTRY_ENABLED**: Enable Sentry error tracking (set to any value to enable)
+- **GITINGEST_SENTRY_DSN**: Sentry DSN (required if Sentry is enabled)
+- **GITINGEST_SENTRY_TRACES_SAMPLE_RATE**: Sampling rate for performance data (default: "1.0", range: 0.0-1.0)
+- **GITINGEST_SENTRY_PROFILE_SESSION_SAMPLE_RATE**: Sampling rate for profile sessions (default: "1.0", range: 0.0-1.0)
+- **GITINGEST_SENTRY_PROFILE_LIFECYCLE**: Profile lifecycle mode (default: "trace")
+- **GITINGEST_SENTRY_SEND_DEFAULT_PII**: Send default personally identifiable information (default: "true")
