Continue adding some profiles of your relatives as you have done. Remember to add sources for each profile. Try not to create duplicate profiles because wikitree wants only one profile for each person, which will hopefully get you connected at some time to ancestors that are already added on wikitree and you can check their profiles, possible adding new resources. Family search is free to use, has lots of sources to check, just needs a login with no subscription.
Welcome to wikitree, take it slow, don't get frustrated. It does take a little bit to understand some parts of wikitree. Ask in g2g if you have questions or reach out to your greeters or a mentor. We are all willing to help new members. We all remember what it was like for us when we got started.
