You have just caught Wappler in a transition between user interface design for 3.. to 4.. so unfortunately documentation is just catching up, otherwise would suggest a fantastic Getting Started course by community member @mebeingken
There are a few differences within the UI but not so many as that you could not begin by using the above course to get an understanding of how things are put-together. Ken may correct me and inform otherwise, also I believe he is in the process of converting the course to a 4.. version? Maybe Ken could let you know if and when this may be available.
In the meantime you will have valuable time to play around and become familiar with the interface and layout during your seven day trial period (which can be extended by simply subscribing for a months subscription, or annual, depending on your preference). Otherwise there is the community to help you. First try a quick search as there may well be information related to new users common questions. And for everything else that doesn't have a result don't be shy in asking a question, no matter how dumb you may think it is, we don't mind and are always happy to help.
Hope that gives you some idea of how to get started.
Welcome to Wappler by the way!
