Hi Carla,
Welcome to WikiTree! There are a number of resources to help you get started and when in doubt, just ask. You will find the WikiTree community a very helpful and friendly bunch.
Here is a basic tutorial for beginners:

Here is another series, Welcome to WikiTree:

I found these to be a good starting point and then you can explore the other videos on the WikiTree Channel.
Though the site is packed full of information, I sometimes found it difficult to locate the instructions on how to do something specific from within WikiTree. However, I found that by doing an simple internet search beginning with "WikiTree how to...", it would bring up the top search results with the correct WikiTree page. Then I just bookmarked them so that I can find them easily the next time I need them.
The other thing I found helpful, was to look at completed profiles to see how they entered information to use as an example for creating profiles.
Be patient as it is a learning curve; however, if you stick with it, I am confident that you will find you love it.
Happy Hunting!
