The Lazarus IDE has built-in help. Apart from that you can get component-specific documentation as well. Freepascal Runtime Library documentation: https://lazarus-ccr.sourceforge.io/docs/rtl/ https://lazarus-ccr.sourceforge.io/docs/rtl/ Lazarus Component Library: https://lazarus-ccr.sourceforge.io/docs/lcl/ https://lazarus-ccr.sourceforge.io/docs/lcl/ Freepascal Component Library: https://lazarus-ccr.sourceforge.io/docs/fcl/ https://lazarus-ccr.sourceforge.io/docs/fcl/ Freepascal Wiki: https://wiki.freepascal.org/Lazarus_Documentation https://wiki.freepascal.org/Lazarus_Documentation Something else I should have added in my original comment: Lazarus has a very capable built-in debugger. That is invaluable if you want to step through and understand how things work.
