Can we still use Arduino WIFI Sheild?

Good morning,

I am using the linked below Arduino WIFI shield for an IOT project.
I want to display sensor values and control an output device through the web.

I have few questions:
1. Can you recommend a start-up guide for this project.
2. How can I use it with Arduino IOT cloud ?

Thanks in advance

only specific boards can be used with Arduino IoT cloud

With this shield I once did a basic project. I changed the color of a 10 mm LED through web (using both PC and mobile). After the revolution of ESP8266, nobody really uses it that much.
