Vala - Documentation
We're still working on documenting the whole language. The current draft can be found at Manual. It covers most of the language and is heavily annotated, but may contain mistakes.

If you want some tips before start hacking in Vala, take a tutorial and see what you can do with this.
GTK+ Kick Start Tutorial for Vala (Screencast)
The Vala Guide (A work in progress.)
Vala tutorials (a series of Video tutorials)
Introduction to asynchronous functions (blog article, in spanish)
Vala Programming Tutorial - Part 1 (in Persian)
Tutorial for beginners and code samples - GNOME Developer Platform
Getting Started - Elementary OS tutorial, covering build system, packaging and Gtk+ GUI applications
Flappy GNOME Tutorial - GTK+ is not a framework for animated games, but this tutorial shows the use of CSS in GTK+ 3.8+ by pushing it to its limits in a fun way
If you find any mistakes in the tutorials on wiki.gnome.org please feel free to correct them.
Genie is another programming language supported by the Vala compiler with a syntax closer to Python.
Genie Tutorials, Blogs and Code Examples - a page listing links to numerous tutorials, articles, blogs, code examples and projects
Developing Genie - a useful starting point if you want to improve the Genie scanner and parser, includes communication channels for developers and a detailed guide on downloading and compiling the Vala source code
List Of Bindings - The list aims to be comprehensive. Bindings are listed by how they are distributed: upstream libraries; Vala; the Vala Extra VAPIs repository and individuals
Generating Bindings - Using GObject introspection to generate a binding
Writing VAPI files manually - A document that explains how to write VAPI files for a C library manually, without GObject introspection

If you have trouble compiling an example try the latest release of Vala. Some distributions ship with older versions of Vala which may lack some features. Also make sure that the respective libraries are installed along with their header files (e.g. *-devel packages on RedHat/Fedora/SuSE, *-dev packages on Debian/Ubuntu).
