Documentation for Tales is right here…
The Documentation area of this website contains guides for bloggers and WordPress admins. It includes a basic introduction and how-to guides for theme installation and customisation. If you’ve used WordPress before it’s a piece of cake.
If you’re looking to build on top of Tales, or create a child theme, check out the Developers section. This is full of technique details, including a CSS pattern library for reusable components.
