GIMP User Manual

GIMP comes with a built-in help system, available in dozens of languages. Once you have started the program, press F1 for context-sensitive help. You may have to install the help pages from a separate package (gimp-help), depending on how your version of GIMP was packaged.

The manual is also available online on a dedicated website.
