Hi Tim,
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 with a lot of information, Welcome to WikiTree:

I found these to be a good starting point and then you can explore the other videos on the WikiTree Channel.
There are also monthly New Member Q and A sessions held on Zoom.

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 by doing an simple internet search beginning with "WikiTree how to...", it would bring up the top search results with the correct WikiTree page. I then bookmark them so that I can find the instructions easily the next time I need them.
Another great way to become acquainted with WikiTree is to sign up for the Profile Improvement Program (PIP). The goal of the Voyage is to develop the skills needed to improve profiles using the community developed guidelines. You as the PIP Voyager are matched up with a Voyage Guide who will help guide you on how to build and improve one of your profiles on your watchlist. It is a great learning tool as well as a handy badge to have if you eventually want to join any of the Special Project teams later on.

Lastly, take a look at completed profiles to see how they entered information to use as an example for creating profiles. Here is a link to a page that has a few examples.

Be patient as it is a learning curve; however, if you stick with it, I am confident that you will you begin to love it.
Happy WikiTreeing!
