We know you are eager to try out your new board but before you can start using the Portenta H7 to run Arduino sketches you need to configure your computer and the Arduino IDE.

 One of the benefits of the Portenta H7 is that it supports different types of software cores. A core is the software API for a particular set of processors. It is the API that provides functions such as digitalRead(), analogWrite(), millis() etc. which directly operate on the hardware.

 ## Portenta and The Arduino Core
-The Portenta H7 is equipped with two Arm Cortex ST processors (Cortex-M4 and Cortex-M7) which run the Mbed OS.  Mbed OS is an embedded real time operating system (RTOS) designed specifically for microcontrollers to run IoT applications on low power. A real-time operating system is an operating system designed to run real-time applications that process data as it comes in, typically without buffer delays. [Here you can read more about real time operating systems](https://www.ni.com/en-us/innovations/white-papers/07/what-is-a-real-time-operating-system--rtos--.html).

-The Arduino core for the Portenta H7 sits on top of the Mbed OS and allows to develop applications using Mbed OS APIs which handle for example storage, connectivity, security and other hardware interfacing. [Here you can read more about the Mbed OS APIs](https://os.mbed.com/docs/mbed-os/v5.15/apis/index.html). However, taking advantage of the Arm® Mbed™ real time operating system's powerful features can be a complicated process. Therefore we simplified that process by allowing you to run Arduino sketches on top of it.

 ### Configuring the Development Environment
 In this section, we will guide you through a step-by-step process of setting up your Portenta board for running an Arduino Sketch that blinks the built-in RGB LED.

 ### 1. The Basic Setup
 Let's begin by Plug-in your Portenta to your computer using the appropriate USB C cable. Next, open your IDE and make sure that you have the right version of the Arduino IDE downloaded on to your computer.
 
 ![The Portenta H7 can be connected to the computer using an appropriate USB-C cable](assets/por_ard_gs_basic_setup.svg)
 
 ### 2. Adding the Portenta to the List of Available Boards
-In your Arduino IDE, open the board manager and search for "portenta".  Find the Arduino mbed-enabled Boards library and click on "Install" to install the latest version of the mbed core (1.2.3 at the time of writing this tutorial).

 ### 3. Uploading the Classic Blink Sketch
 Let's program the Portenta with the classic blink example to check if the connection to the board works. There are two ways to do that:
 
--   In the classic Arduino IDE open the blink example by clicking the menu entry **File > Examples > 01.Basics > Blink**. You need to swap LOW and HIGH pin values as the built-in LED on Portenta is turned on by pulling it LOW.
--   In the Arduino IDE copy and paste the following code into a new sketch in your IDE.

 ### 4. Upload the Blink Sketch 
 Now it's time to upload the sketch and see if the LED will start to blink. Make sure you select Arduino Portenta H7 (M7 core) as the board and the port to which the Portenta H7 is connected. If the Portenta H7 doesn't show up in the list of ports, go back to step 1 and make sure that the drivers are installed correctly. Once selected click Upload. Once uploaded the built-in LED should start blinking with an interval of 1 second.
 
-**Note:** The Portenta H7 has an M7 and an M4 processor which run separate cores. That's why you need to select the one to which you want to upload your sketch to (check out the tutorial [Dual core processing](https://docs.arduino.cc/tutorials/portenta-h7/dual-core-processing) to learn more about Portenta's processors).
