 Following is the simplest use case:
 
 ```go
-	name := "Single bar:"
 	// Star mpb's rendering goroutine.
 	// If you don't plan to cancel, feed with nil
 	// otherwise provide context.Context, see cancel example
 	p := mpb.New(nil)
-	// Set custom format, the default one is "[=>-]"
+	// Set custom width for every bar, which mpb will contain
+	// The default one in 70
+	p.SetWidth(80)
+	// Set custom format for every bar, the default one is "[=>-]"
 	p.Format("╢▌▌░╟")
+	// Set custom refresh rate, the default one is 100 ms
+	p.RefreshRate(120 * time.Millisecond)
 
-	bar := p.AddBar(100).PrependName(name, 0).AppendPercentage()
+	// Add a bar. You're not limited to just one bar, add many if you need.
+	bar := p.AddBar(100).PrependName("Single Bar:", 0).AppendPercentage()
 
 	for i := 0; i < 100; i++ {
 		time.Sleep(time.Duration(rand.Intn(100)) * time.Millisecond)
 		bar.Incr(1)
 	}
 
+	// Don't forget to stop mpb's rendering goroutine
 	p.Stop()
+
+	// You cannot add bars after p.Stop() has been called
+	// p.AddBar(100) // will panic
 ```
