The hardest part is getting started 😊. You don't need to learn HTML layout or interface modeling standards to create a page for your cat, business, or announcement.
Think about what you want to tell your website visitors and in what order. Then go to Control, create a new page, and put it all together. Next, add some intonation - emphasize the important parts, publish it, and that's it. Show it to your parents, friends, colleagues, or cat. I'm sure you'll want to "tweak here and there," try a different color, or add a photo, and that's where the whole "rabbit hole" begins...
