A.1.3 How to install the gitman info manual

Git’s manpages can be exported as an info manual called gitman. Magit’s own info manual links to nodes in that manual instead of the actual manpages because Info doesn’t support linking to manpages.

Unfortunately some distributions do not install the gitman manual by default and you will have to install a separate documentation package to get it.

Magit patches Info adding the ability to visit links to the gitman Info manual by instead viewing the respective manpage. If you prefer that approach, then set the value of magit-view-git-manual-method to one of the supported packages man or woman, e.g.:

(setq magit-view-git-manual-method 'man)
