func main() {
    // Initialize Atatus tracer with values from environment
    tracer := atatus.DefaultTracer
    tracer.Service.LicenseKey = os.Getenv("ATATUS_LICENSE_KEY")
    tracer.Service.AppName = os.Getenv("ATATUS_APP_NAME")
    tracer.Service.Tracing = os.Getenv("ATATUS_TRACING")

    router.Use(atgin.Middleware(router))

    // Register routes
    router.GET("/", handleRequest)

    // Start server
    router.Run(":8080") 
}

func handleRequest(c *gin.Context)  {
    // The context from  c.Request.Context() should be propagated to downstream operations,
