+# 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).

+# Blinky Mbed OS example
+
+The example project is part of the [Arm Mbed OS Official Examples](https://os.mbed.com/code/) and is the [getting started example for Mbed OS](https://os.mbed.com/docs/mbed-os/v5.14/quick-start/index.html). It contains an application that repeatedly blinks an LED on supported [Mbed boards](https://os.mbed.com/platforms/).
+
+You can build the project with all supported [Mbed OS build tools](https://os.mbed.com/docs/mbed-os/latest/tools/index.html). However, this example project specifically refers to the command-line interface tool [Arm Mbed CLI](https://github.com/ARMmbed/mbed-cli#installing-mbed-cli).
+(Note: To see a rendered example you can import into the Arm Online Compiler, please see our [import quick start](https://os.mbed.com/docs/mbed-os/latest/quick-start/online-with-the-online-compiler.html#importing-the-code).)
+
+1. [Install Mbed CLI](https://os.mbed.com/docs/mbed-os/latest/quick-start/offline-with-mbed-cli.html).
+
+1. Clone this repository on your system, and change the current directory to where the project was cloned:
+
+    ```bash
+    $ git clone git@github.com:armmbed/mbed-os-example-blinky && cd mbed-os-example-blinky
+    ```
+
+    Alternatively, you can download the example project with Arm Mbed CLI using the `import` subcommand:
+
+    ```bash
+    $ mbed import mbed-os-example-blinky && cd mbed-os-example-blinky
+    ```
+
+
+## Application functionality
+
+The `main()` function is the single thread in the application. It toggles the state of a digital output connected to an LED on the board.
+
+## Building and running
+
+1. Connect a USB cable between the USB port on the board and the host computer.
+2. <a name="build_cmd"></a> Run the following command to build the example project and program the microcontroller flash memory:
+    ```bash
+    $ mbed compile -m <TARGET> -t <TOOLCHAIN> --flash
+    ```
+The binary is located at `./BUILD/<TARGET>/<TOOLCHAIN>/mbed-os-example-blinky.bin`.
+
+Alternatively, you can manually copy the binary to the board, which you mount on the host computer over USB.
+
+Depending on the target, you can build the example project with the `GCC_ARM`, `ARM` or `IAR` toolchain. After installing Arm Mbed CLI, run the command below to determine which toolchain supports your target:
+
+```bash
+$ mbed compile -S
+```
+
+## Expected output
+The LED on your target turns on and off every 500 milliseconds.
+
+
+## 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.
