Finally I found an explanation of this piece of text that you can see in every publishing tool every once in a while:

Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry’s standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum.

While lipsum.com does a good job, it’s not really user-friendly and it also contains ads…
I did some exploring and found this other tool. It’s ad-free and quite straightforward, and I wanted to suggest you show it alongside the other one:

This tool allows you to create dummy text quickly and easily (and it doesn’t cost a thing): -)😊
