-It is recommended that you consider the startup time a box needs before it
-is ready. The simplest approach is to use the `boxutil.WaitForReady` function:
-
-```go
-err := boxutil.WaitForReady(ctx, faceboxClient)
-if err != nil {
-    log.Fatalln("error waiting for box:", err)
-}

-A more advanced solution is to get notified whenever the status of a box changes
-using the `boxutil.StatusChan` feature:
-
-```go
-go func(){
-    statusChan := boxutil.StatusChan(ctx, faceboxClient)
-    for {
-        select {
-        case status := <-statusChan:
