I need your help

Hello, I am a new user. Can you please tell me how do I add a device to particle io?
I would appreciate step by step instructions!
Also, I’m not very good at it, so I studied a little information on the Internet to understand how it works. In an article about iot remote control says the following: In many cases, devices used in IoT environments were manufactured without the capability to easily be connected to the Internet. These devices need to be modified so they can be connected to IoT networks. That is, the device can be modified and I will be able to control it remotely? Or am I misunderstanding?

Hi Suzi-
Thanks for asking!
Do you have a Particle device? Any Particle device is already an IOT device that can be connected to the internet. You do not need to modify them at all for the connection.

As for setup, I suggest using the Device Setup tool and checking out the “Getting Started” section of Particle documentation.
