Where can I find good ConTeXt documentation

Shameless plug: I write a regular (rather semi-regular) article series in tugboat on specific ConTeXt topics aimed at beginners. Articles so far:

• Font Styles
• Table Macros I
• Table Macros II
• Indentation
• Conditional Processing
• Paper Setup
• Images

The PRAGMA Advanced Document Engineering site has a lot of documentation and examples on the finer details of how to use ConTeXt for particular applications and effects. I discovered it during a search for documentation on how to use Layers for cover layouts, which lead me to the excellent PDF It's in the details.

The context reference manual is somewhat outdated, but we are (slowly) working on improving and extending it. It is a community project, and three chapters have already been improved:

• Chapter on typography
• Chapter on fonts
• Chapter on pagedesign
