@estelaris I can work on this one

@estelaris I took a look at the live page and noticed there are currently no screenshots or images anywhere in the article.

It’s great that we already have a video under the Demo section. That said, screenshots are quick to implement and would immediately improve clarity, and scannability for users who don't want to click the play button.

@aialvi feel free to get provide screenshots, add them here and we will update the Wordpress article
