Great! Thanks. Didn’t know about it.

I was reading just only manual page - suricata-update(1).  
There is no information about [https://suricata-update.readthedocs.io/](https://suricata-update.readthedocs.io/).  
Would be nice if there was that link.

Finally, I’ve found how that manpage was created for Debian dist:

1. [https://salsa.debian.org/pkg-suricata-team/pkg-suricata-update/-/blob/master/debian/rules](https://salsa.debian.org/pkg-suricata-team/pkg-suricata-update/-/blob/master/debian/rules)
2. then via [`help2man`](https://wiki.debian.org/ManualPage/help2man) which adds `--help` to program, so it becomes `suricata-update --help`

For groff(7) output (which produces `help2man`), URL probably should be placed within `.UR` and `.UE` macros, see [groff\_man(7)](https://www.man7.org/linux/man-pages/man7/groff_man.7.html).  
In case it is entirely rewritten in mdoc(7) then need to use [.Lk macro](https://mandoc.bsd.lv/man/mdoc.7.html#Lk).
