When you go to https://familysearch.org/wiki, notice on the right border the words "Show Me How".
When you click it, a box flies out where you can click one of the choices to indicate what you want to learn about. Or you can enter a question in the search box. Let's try the Country Page Overview to see how it works.
It jumps to Sweden Genealogy and we click Next to begin the tour.
The tour takes you to various parts of the page and provides an explanation. To progress through the tour, you just click Next on each explanatory box. You can also click Back if you want to return to an earlier box. Or click the small x in the top right to leave the tour.
It's a nice way to get a feel for various aspects of the wiki that you might not have stumbled on on your own. When you finish a tour, a box pops up with possible next steps.
It's nice to see more tools to help us understand how to get the most from FamilySearch.org. The folks there are trying to make it as easy for us as possible.
And, as long as I'm writing about ways to learn to use the website, you might also notice the lightbulb icons in the lower right corner of Family Tree pages, Record Search, the Memories Gallery, and (for members of The Church of Jesus Christ of Latter-day Saints) your Temple reservation page. Click the icons to learn how to use the page you are on.
You no longer need to wonder how to do the basic FamilySearch tasks. Help is at your fingertips.
