 The instrumentation captures email addresses and metadata to help with debugging and monitoring, while avoiding sensitive email content.
 
-## Configuration
-
-```ts
-instrumentResend(resend, {
-  tracerName: "my-service",
-  tracer: myCustomTracer,  // optional: bring your own tracer
-});
-```
-
-- `tracerName`: Custom name for the tracer (defaults to `@kubiks/otel-resend`)
-- `tracer`: Use an existing tracer instance instead of creating a new one
