After you sign the honor code and the other things, start with yourself, there's a template where you enter name, where born and when, and other information. There was likely a birth registration, a birth certificate, had a number assigned to it.
SOURCES would be where the birth certificate is located (State capitol archives, usually) and that is quite often available (depending on what state you were born in if born in United States) at www.familysearch.org
SOURCES are put into the profile in order that anyone who has questions or doubts can go look at the material for themselves. These are hyperlinked automatically if you copy the "Citation" information provided by familysearch, the whole thing it provides.
THIS site is available without payment, free to use, and use the SAME email (user name) and password you used when you signed up at Wikitree
In fact each time you logon into Wikitree, use the SAME email and password. That's important.
You can keep yourself private, using black or red privacy setting.
Once you have that done, profile each parent, and again you can quite possibly find info on them at www.familysearch.org
There are dozens of PM at Wikitree who WILL be willing to assist you in navigating Wikitree and in formation of the profiles. It WILL take some time to become used to the WT system, but practice, practice, practice.
