Try not to be discouraged about things going slowly, at first. We all had to learn and we were all slow and made mistakes at first. I think I was creating no more than two profiles a day in my early days. Even now, I still take my time and enjoy the process rather than try to hurry. I think it is commendable that you want to learn and to format your profiles well. Good attitude and willingness to learn are very important! Remember this is a hobby and should be fun and not stress you out. Try to keep things basic and simple at first. Bells & whistles can always be added later.
Start by adding your data, as accurately as possible, to the data fields. Try to add sources for the data--birth, marriage, death, mainly--in the sources box. When you click submit, you will get a little basic bio. Not much, but a start. You can use simple declarative sentences to add more information to the bio.
Once you feel comfortable, you might want to install the WikiTree Browser Extension. One of its features is the "auto bio." You would be able to just click a button at the top of the bio edit box and you will be provided a bit better bio based on the data and sources you added. You can then edit that.
It would help us to help you if you would be more specific about what you need to or want to learn how to do. You have been directed to many help pages, but if we knew exactly what you needed help with, one of us could send you to the exact one you needed, or explain to you how to do it, or provide you with an example. The people here on G2G were extremely helpful to me in my early days here and I'm sure they would be to you also.
All the best to you!
