Hi Rick,
Yes, there are tutorials. They’re mentioned in the dialog that Xway displays when it is first run (or you can choose Readme from the Help menu).
For written tutorials: choose Xway Resources from Xway’s Help menu, then click on Tutorials.
For video tutorials: we’re working on these, but there are draft versions available:
Xway Tutorial
Xway Menu Tutorial
Xway Flexbox Tutorial
The first (introductory) tutorial shows how to create a simple flexible website (and includes information on centring text and setting font sizes).
There are also free templates that you can use as a starting point, although it’s probably a good idea to work through the introductory tutorial as well.
