+## How to use it

+```go
+package main
+
+import (
+	"fmt"
+	"time"
+
+	"tinygo.org/x/tinyfont/proggy"
+	"tinygo.org/x/tinyterm"
+	"tinygo.org/x/tinyterm/displays"
+)
+
+var (
+	font = &proggy.TinySZ8pt7b
+)
+
+func main() {
+	display := displays.Init()
+	terminal := tinyterm.NewTerminal(display)
+
+	terminal.Configure(&tinyterm.Config{
+		Font:              font,
+		FontHeight:        10,
+		FontOffset:        6,
+		UseSoftwareScroll: displays.NeedsSoftwareScroll(),
+	})
+	for {
+		time.Sleep(time.Second)
+
+		fmt.Fprintf(terminal, "\ntime: %d", time.Now().UnixNano())
+		terminal.Display()
+	}
