+## Essential Pre-Setup Checklist
 
-* If you haven't done so, start by checking the [Arduino PLC IDE Setup and Board's License Activation](https://docs.arduino.cc/software/plc-ide/tutorials/plc-ide-setup-license#instructions) tutorial.
-* Make sure you've installed the latest version of the **Arduino PLC IDE** software.
-* Make sure you're using a working USB cable that supports data transfer.
-* When downloading the runtime, or connecting to the device, make sure you're [targeting the correct port](#about-ports).
-* When opening a project created with an earlier version of the PLC IDE, some issues may occur. Try creating a new project (**File > New Project**) to see if this resolve the issue.
-* You need **valid license** to download code to the device:
-  * Licenses for Portenta Machine Control are [available in the store](https://store.arduino.cc/products/plc-key-portenta-machine-control). Instructions for license activation [are available here](https://docs.arduino.cc/software/plc-ide/tutorials/plc-ide-setup-license#6-license-activation-with-product-key-portenta-machine-control).
-  * Arduino Opta is a pre-licensed product, just follow the [activation instructions](https://docs.arduino.cc/software/plc-ide/tutorials/plc-ide-setup-license#7-license-activation-with-pre-licensed-products-opta).

 Initially, only this port will be available. Target this port when [downloading the runtime](https://docs.arduino.cc/software/plc-ide/tutorials/plc-ide-setup-license#4-download-the-runtime).
 
-#### Virtual serial port (created by runtime)

-When the runtime has been downloaded to your device, an additional (virtual) port will appear. Because the virtual port is created after the serial port, it will usually have a **higher port number**. Target this port when [configuring the Modbus communication](https://docs.arduino.cc/software/plc-ide/tutorials/plc-ide-setup-license#5-connect-to-the-device).
