Note that, FWIW, Free Pascal today comes with the same manuals - a user's guide (telling you how to install and use the compiler, the IDE and the various tools), a programmer's guide (telling you implementation details for the language), a language reference (explaining the language itself, in theory you can make your own compiler from that), a runtime library reference (what the name implies) and a framework reference (reference for the extra libraries that usually come with FPC). Also there is a reference for the documentation generator in case you need to write docs yourself. https://www.freepascal.org/docs.var https://www.freepascal.org/docs.var
