+#### Graceful shutdown timeout
+
+If your application requires postponing its shutdown process, Terminus can be handle it for you.
+This setting can prove particularly beneficial when working with an orchestrator such as Kubernetes.
+By setting a delay slightly longer than the readiness check interval, you can achieve zero downtime when shutting down containers.

+```typescript
+@@filename(health.module)
+@Module({
+  imports: [
+    TerminusModule.forRoot({
+      gracefulShutdownTimeoutMs: 1000,
+    }),
+  ]
+})
+export class HealthModule {}
