This is one of those “oh, there it is” posts, more for myself than anyone else. Anyway, if you use SSB from a shell (perhaps you run your own SSB Pub, for example), you might want to run this style of command:
ssb-server publish --type about --about "$(ssb-server whoami | jq .id -r)" --name "Some Server" --description "I'm just some server, you know"
As long as you have
--description in there, you should be good to go!
