+## Setup
+Fork this repo and use [GitHub Pages](https://help.github.com/en/articles/configuring-a-publishing-source-for-github-pages) to deploy.
+
+## Testing it Locally
+Also you can run and test it locally. Here is a quick write-up of the necessary steps:
+
+1.	Download and install Ruby installer for Windows (2.4.3): https://rubyinstaller.org/downloads/
+2.	Launch command, install Jekyll and Bundler: 'gem install jekyll bundler'
+3.	Git clone the doc repo: 'git clone https://github.com/Microsoft/azure-iot-developer-kit.git'
+4.	Go into the doc repo cloned and update the submodules: 'git submodule update --init --recursive'
+5.	Go into the /docs folder within the repo, and install the necessary bundles for Jekyll: 'bundle install'
+6.	Now in the /docs folder, start the local server: 'bundle exec jekyll serve'
+7.	Open 'http://localhost:4000' in browser you should see the local docs
+8.	Update any markdown or update the image fill trigger the auto rebuild, you should reload the browser to see the changes.

+
+## Overview
+
+The MXChip IoT DevKit has two UART serial ports. One is connected to the USB port and allows you to send serial data over a USB cable, such as debugging information. The other is available from Pins 1 and 2 on the finger connector and allows you to connect the device to other modules that send data over serial.
+
+## Sending data over the USB serial port
+
+The USB serial port is available using the `Serial` global variable, and this uses the `UART_0` serial port. The API for this is identical to the standard Arduino `Serial` API, which you can read about in the [Arduino Serial communication docs](https://www.arduino.cc/reference/en/language/functions/communication/serial/).
+
+```c
+// Open the serial port at a speed of 115200 baud
+Serial.begin(115200);
+
+// Send a message over the serial connection
+Serial.write("Hello");
+```
+
+You can monitor data sent over this serial connection using the VS Code Serial Monitor, available from the command palette by selecting *Arduino: Open Serial Monitor*. The board will send logging information over this port in addition to the data you send.
+
+![The serial monitor showing logging messages and hello]({{"/assets/images/how-to/serial/serialmonitor.png" | absolute_url }})
+
+## Sending data over the finger connector serial port
+
+The second UART serial port is available via the finger connector on the large pins 1 and 2.
+
+![The MXChip finger connector with pin 1 marked as TX and pin 2 marked as RX]({{"/assets/images/how-to/serial/board_annotated_pins.png" | absolute_url }})
+
+| Pin | Usage         |
+| --- | ------------- |
+| 1   | TX - Transmit |
+| 2   | RX - Receive  |
+
+Pin 1 is the transmit (TX) pin, and is used to send serial data to an external module. This pin should connect to the **RX** pin on the external module.
+
+Pin 2 is the receive (RX) pin, and is used to receive serial data from an external module. This pin should connect to the **TX** pin on the external module.
+
+> NOTE: The TX pin on the MXChip IoT DevKit needs to connect to the RX pin on an external module, and vice versa. The signal transmitted needs to go to a receiving pin.
+
+Once the device is connected, you will need to declare a new `UARTClass` variable pointing to the second serial port, `UART_1`.
+
+```c
+UARTClass Serial1(UART_1);
+```
+
+This has the same type as the `Serial` global variable, and uses the same serial API.
+
+```c
+// Open the serial port at a speed of 9600 baud
+Serial.begin(9600);
+
+// Read a byte from the second serial port
+int byte = Serial1.read();
+
+// Send the byte to the USB serial port for debugging
+Serial.write(byte);
+```
