+- Download Simplicity Studio, this is an IDE provided by Silicon Labs. It is designed to simplify the development process for Silicon Labs hardware platforms. Download latest version [here](https://www.silabs.com/developers/simplicity-studio).
+
 - Open Simplicity Studio and create a new project by clicking on **File > New > Silicon Labs Project Wizard**.

-|   **Field**   | **Setting** |
-| :-----------: | :---------: |
-| Target Boards |  BRD4318A   |
+- Set the following project configurations and click on *Next*.

+
+#### Change the Serial Port Pinout
+
+The default pinout is **PA8 > TX** and **PA9 > RX**, but we need to change it to **PA4 > TX** and **PA5 > RX**, so they correspond to the **D0** and **D1** of the standard Nano layout.
+
+- Delete the default `USART0` setting:

+![Delete the default USART setting](assets/quit-usart.gif)
+
+- Add the new setting:

+![Add the new USART setting](assets/add-usart.gif)
+
+- Save your project with the new configurations.
+
+#### Disable USART Flow Control
+
+- Open the `<project-folder>/config/sl_uartdrv_usart_vcom_config.h` file.
+  
+- Modify the `SL_UARTDRV_USART_VCOM_FLOW_CONTROL_TYPE` variable as follows:
+```
+#define SL_UARTDRV_USART_VCOM_FLOW_CONTROL_TYPE uartdrvFlowControlNone
+```
+
+![Flow Control Disabled](assets/flow-ctrl.png)
+
+#### Build and Flash the Project
+
+- In the upper menu navigate to **Project > Build Project** to compile and build the RCP firmware.
