Red is still a young project, so its documentation lacks depth and examples. However, Red's popularity is growing rapidly, so this situation is expected to improve in the near future.
A number of documentation links can be found at https://www.red-lang.org/p/documentation.html, among which is the official Red documentation, also found at https://doc.red-lang.org/ (which is still under construction).
The following websites can help you out when you need more examples or explanations:
- The Red By Example site (http://www.red-by-example.org/index.html), maintained by Arie Van Wingerden and Mike Parr
- The Red Beginners Reference Guide at http://www.mycode4fun.co.uk, maintained by Alan Brack
- Red documentation in the form of a Notebook at http://helpin.red/, by André Ungaretti
