+# Contributing to Mbed OS
+
+Mbed OS is an open-source, device software platform for the Internet of Things. Contributions are an important part of the platform, and our goal is to make it as simple as possible to become a contributor.
+
+To encourage productive collaboration, as well as robust, consistent and maintainable code, we have a set of guidelines for [contributing to Mbed OS](https://os.mbed.com/docs/mbed-os/latest/contributing/index.html).

+# Getting started example for Mbed OS
+
+This guide reviews the steps required to get Blinky with the addition of dynamic OS statistics working on an Mbed OS platform. (Note: To see a rendered example you can import into the Arm Online Compiler, please see our [quick start](https://os.mbed.com/docs/mbed-os/latest/quick-start/online-with-the-online-compiler.html#importing-the-code).)
+
+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:
+
+```
+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:
+
+```
+[snip]
+
+Image: ./BUILD/K64F/GCC_ARM/mbed-os-example-blinky.bin
+```
+
+### 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. The main thread will additionally take a snapshot of the device's runtime statistics and display it over serial to your PC. The snapshot includes:
+
+* System Information:
+    * Mbed OS Version: Will currently default to 999999
+    * Compiler ID
+        * ARM = 1
+        * GCC_ARM = 2
+        * IAR = 3
+    * [CPUID Register Information](#cpuid-register-information)
+    * [Compiler Version](#compiler-version)
+* CPU Statistics
+    * Percentage of runtime that the device has spent awake versus in sleep
+* Heap Statistics
+    * Current heap size
+    * Max heap size which refers to the largest the heap has grown to
+* Thread Statistics

+
+### Output
+
+To view the serial output you can use any terminal client of your choosing such as [PuTTY](http://www.putty.org/) or [CoolTerm](http://freeware.the-meiers.org/). Unless otherwise specified, printf defaults to a baud rate of 9600 on Mbed OS.
+
+You can find more information on the Mbed OS configuration tools and serial communication in Mbed OS in the related [related links section](#related-links).
+
+The output should contain the following block transmitted at the blinking LED frequency (actual values may vary depending on your target, build profile, and toolchain):
