### note
I installed keyring with pip install --user, so my keyring binary is at ~/.local/bin/keyring

# add public github token to keyring
[trey|d3v ~]% keyring set gister public_oauth
Password for 'public_oauth' in 'gister': <paste github oauth token here>
[trey|d3v ~]% keyring get gister public_oauth
