The Church of Jesus Christ of Latter-day Saints, also often called “the Mormons”, owns the very popular FamilySearch.org web site. This web site has extensive online records, downloadable software, and a huge amount of "how to" information. Best of all, everything on the site is available free of charge. Indeed, it is one of the most popular genealogy web sites in the world.
One item added a few months ago to FamilySearch.org is called a wiki. Many people may find that word to be a bit confusing, as "wiki" is not yet a common word in the English language. I would suggest it should be, as a wiki is a very powerful, yet easy to use, online resource. The FamilySearch.org wiki is devoted to genealogy.
