I find that Hugo should contain more links to relevant documentation of features in other tools/documentations. Please let me know if we don't want that and I'll stop. In this specific case I read about `.mailmap` in the Hugo docs and as a developer knew what was meant, but I think less dev-y users might not understand this. Instead of starting to add paragraphs about the format maybe it's ok to link to the features docs? As I said, let me know if that is overkill/bloat. It would make my life easier than seeing a word and googling it :)
(for instance, if we link to git in this case we don't need to add extra-documentation about what the mailmap file should look like and what should be in there)
