The FamilySearch.org website has some instructions for those who are just getting started in doing family research. These pages are designed to help people who are logging into the website for the first time but will also help those who have questions about what kinds of activities are appropriate for different skill levels. If you have a moderate skill level, you may wish to click on the main menu bar that includes options to "Get Involved."
Exploring these options gives those who are looking for ways to help such as helping to correct the index for the 1950 U.S. Federal Census Project.
If you need help with finding your ancestors and relatives in a specific state, there are links to getting started in the FamilySearch.org Research Wiki.
You just need to choose a place to start. See https://www.familysearch.org/en/wiki/Main_Page
