-# 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.
-
-## Export the project to Keil MDK, and debug your application
-
-From the command-line, run the following command:
-
-```
-mbed export -m K64F -i uvision
-```
-
-To debug the application:
-
-1. Start uVision.
-1. Import the uVision project generated earlier.
-1. Compile your application, and generate an `.axf` file.
-1. Make sure uVision is configured to debug over CMSIS-DAP (From the Project menu > Options for Target '...' > Debug tab > Use CMSIS-DAP Debugger).
-1. Set breakpoints, and start a debug session.
-

-
-## Troubleshooting
-
-1. Make sure `mbed-cli` is working correctly and its version is `>1.0.0`
-
- ```
- mbed --version
- ```
-
- If not, you can update it:
-
- ```
- pip install mbed-cli --upgrade
- ```
-
-2. If using Keil MDK, make sure you have a license installed. [MDK-Lite](http://www.keil.com/arm/mdk.asp) has a 32 KB restriction on code size.
