 ## Overview
 
-The Opta™ is a secure, easy-to-use micro Programmable Logic Controller (PLC) with Industrial Internet of Things (IIoT) capabilities. It can be programmed with the [Arduino PLC IDE](https://www.arduino.cc/pro/software-plc-ide/), a tool that simplifies programming the device through any of the five programming languages defined by the IEC 61131-3 standard. 
+The **Opta™** is a secure, easy-to-use micro Programmable Logic Controller (PLC) with Industrial Internet of Things (IIoT) capabilities. The **Portenta Machine Control** is a centralized, energy-efficient industrial control unit capable of operating equipment and machinery. Both devices can be programmed with the [Arduino PLC IDE](https://www.arduino.cc/pro/software-plc-ide/), a tool that simplifies programming the device through any of the five programming languages defined by the IEC 61131-3 standard.

In case we are using Opta™ with the Arduino PLC IDE and we want to start programming the device using the Arduino IDE and the rest of the Arduino ecosystem tools, we need to partition the memory of the device to enable all of the available features.

 ## Memory Partitioning
 
-Memory partitioning involves dividing the available memory of a device into separate regions or partitions, each serving a specific purpose. This process is used for managing memory efficiently and ensuring that different programs or functionalities of the device can coexist without interfering each other. In the context of the Opta™, partitioning the memory allows the device to accommodate different functionalities, such as its Wi-Fi® module firmware, Over-The-Air (OTA) updates functionality, and certificates storage, while still providing memory space for user programs developed in the Arduino IDE and the Arduino programming language.

 Now, we will guide the process of partitioning an Opta™'s memory to enable the full range of its functionalities to be programmed using the Arduino IDE and the Arduino programming language.
 
 ## Instructions
 
 ### Setting Up the Arduino IDE 
 
-This tutorial requires the latest version of the Arduino IDE; we can download it [here](https://www.arduino.cc/en/software). In the Arduino IDE, we need to install the core for Opta™ devices; this can be done by navigating to **Tools > Board > Boards Manager** or clicking the Boards Manager icon in the left tab of the IDE. In the Boards Manager tab, search for `opta` and install the latest `Arduino Mbed OS Opta Boards` version.

+To partition the memory of an Opta™ device, you need an Arduino sketch that includes memory partition operations and a certificate file. These files can be downloaded directly from the [Software Requirements section](#software-requirements) or [here](assets/memory_partitioning.zip). Ensure both files are stored in the same directory, as shown in the following layout:

 The sketch shown above performs four main tasks:
 
 1. **Initialize and erase the QSPI Flash memory**: The sketch initializes the QSPI Flash memory of the Opta™ device and erases its content to prepare the memory for new firmware and data. One of the built-in LEDs of the device is used to indicate the progress of the memory-erasing process.
 
-2. **Create partitions and format them in the QSPI Flash memory**: The sketch creates and formats partitions in the QSPI Flash memory for the Wi-Fi firmware, Over-The-Air (OTA) updates functionality, and certificates storage.
