-# Getting started with Blinky on mbed OS
-
-This guide reviews the steps required to get Blinky working on an mbed OS platform.
-
-Please install [mbed CLI](https://github.com/ARMmbed/mbed-cli#installing-mbed-cli).
-
-## Import the example application
-
-From the command-line, import the example:
-
-```
-mbed import mbed-os-example-blinky
-cd mbed-os-example-blinky
-```
-
-### Now compile
-
-Invoke `mbed compile`, and specify the name of your platform and your favorite toolchain (`GCC_ARM`, `ARM`, `IAR`). For example, for the ARM Compiler 5:
-
-```
-mbed compile -m K64F -t ARM
-```
-
-Your PC may take a few minutes to compile your code. At the end, you see the following result:
-
