@@ -11,13 +11,20 @@ This command shows the hledger manual built in to your hledger version.
 It can be useful when offline, or when you prefer the terminal to a web browser,
 or when the appropriate hledger manual or viewing tools are not installed on your system.
 
-By default it chooses the best viewer found in $PATH
-(preferring info since the hledger manual is large).
-You can select a particular viewer with the `-i`, `-m`, or `-p` flags.
+By default it chooses the best viewer found in $PATH, trying (in this order):
+`info`, `man`, `$PAGER`, `less`, `more`.
+You can force the use of info, man, or a pager with the `-i`, `-m`, or `-p` flags,
+If no viewer can be found, or the command is run non-interactively, it just prints
+the manual to stdout.
+
+If using `info`, note that version 6 or greater is needed for TOPIC lookup. If you are
+on mac you will likely have info 4.8, and should consider installing a newer version,
+eg with `brew install texinfo` (#1770).
