While monitoring the general acceptance of Icaros Desktop from various websites all over the world, our attention stumbled upon this polish page (LINK).
It covers most urgent topics like Icaros installation, polish language/font localization and setting up of AmiBridge (with complete integration of Amiga Forever). We would like to thank author Radzik for his useful guide (Icaros manual does not cover international characters set). International readers may like the english robotranslation here.
