Boards readme files contain all the information needed to get started with a particular board.
Many do. They all should. They vary in quality. Some board README files have no useful information at all; some have old information. Some consist of only a few lines, some are thousands of lines. Some boards don't any any README files.
The board README files are very helpful. Even for me. If I have not worked with a board for a couple of years, the README file brings me back up to speed very quickly.
Unfortunately the content is not consistent, controlled, or properly maintained.
