+# 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:
+
+```

+```
+
+### Program your board
+
+1. Connect your mbed device to the computer over USB.
+1. Copy the binary file to the mbed device.
+1. Press the reset button to start the program.
+
+The LED on your platform turns on and off.
+
+## Troubleshooting
+
+If you have problems, you can review the [documentation](https://os.mbed.com/docs/latest/tutorials/debugging.html) for suggestions on what could be wrong and how to fix it.
