 ## How to Use
 ```go
-// code here
+package main
+
+import (
+	"fmt"
+	"os"
+	"time"
+
+	"gobot.io/x/gobot"
+	"gobot.io/x/gobot/platforms/ble"
+	"gobot.io/x/gobot/platforms/parrot/minidrone"
+)
+
+func main() {
+	bleAdaptor := ble.NewClientAdaptor(os.Args[1])
+	drone := minidrone.NewDriver(bleAdaptor)
+
+	work := func() {
+		drone.On(drone.Event("battery"), func(data interface{}) {
+			fmt.Printf("battery: %d\n", data)
+		})
+
+		drone.On(drone.Event("status"), func(data interface{}) {
+			fmt.Printf("status: %d\n", data)
+		})
+
+		drone.On(drone.Event("flying"), func(data interface{}) {
+			fmt.Println("flying!")
+			gobot.After(5*time.Second, func() {
+				fmt.Println("landing...")
+				drone.Land()
+				drone.Land()
+			})
+		})
+
+		drone.On(drone.Event("landed"), func(data interface{}) {
+			fmt.Println("landed.")
+		})
+
+		time.Sleep(1000 * time.Millisecond)
+		drone.TakeOff()
+	}
+
+	robot := gobot.NewRobot("minidrone",
+		[]gobot.Connection{bleAdaptor},
+		[]gobot.Device{drone},
+		work,
+	)
+
+	robot.Start()
+}

 ## How to Connect
 
-Instructions here...
+The Parrot Minidrone is a Bluetooth LE device.
+
+You need to know the BLE ID of the Minidrone you want to connect to. The Gobot BLE client adaptor also lets you connect by friendly name, aka "RS_1234".
+
+### OSX
+
+To run any of the Gobot BLE code you must use the `GODEBUG=cgocheck=0` flag in order to get around some of the issues in the CGo-based implementation.
+
+For example:
+
+    GODEBUG=cgocheck=0 go run examples/minidrone.go RS_1234
+
+OSX uses its own Bluetooth ID system which is different from the IDs used on Linux. The code calls thru the XPC interfaces provided by OSX, so as a result does not need to run under sudo.
+
+### Ubuntu
+
+On Linux the BLE code will need to run as a root user account. The easiest way to accomplish this is probably to use `go build` to build your program, and then to run the requesting executable using `sudo`.
+
+For example:
+
+    go build examples/minidrone.go
+    sudo ./bb8 RS_1234
+
+### Windows
+
+Hopefully coming soon...
