Trying to figure out commandline usage

I was trying to follow instructions on the main page explaining about local encryption and decryption. Here's what I typed into the terminal.

tama@SERENITY:~$ keybase id maria

tama@SERENITY:~$ man keybase
No manual entry for keybase
See 'man 7 undocumented' for help when manual pages are not available.
tama@SERENITY:~$

I guess this means the public key I received when I first started should be put into some specific directory?

Start with the main-page instructions for local encryption and decryption and compare them with the reported `keybase` commands and the missing `man keybase` entry. Clarify the required public-key setup and command-line usage, then verify that the documented encryption flow works for the reported cases.
