I googled rakudoc and that led to: https://github.com/Raku/rakudoc
which says it's forked from: https://github.com/noisegul/perl6-p6doc So I tried that in m.r.o and it's listed: https://modules.raku.org/search/?q=p6doc So, perhaps you can zef install p6doc? Maybe the doc you read mentioning rakudoc is ahead of the situation in rakudo versions, or at least yours, as well as being ahead of the ecosystem? love, raiph
