@krueger Not in the current form as the help files are downloaded and converted client-side in JavaScript. A script to convert all the docs into a printable PDF sounds like a good idea though.
You can find a somewhat complete documentation of the help file syntax in the README for translators - https://github.com/colobot/colobot-data/...ME.i18n.md
