Can't add the awscli_keyring plugin

[shevaun]

Hey Sam,
Following your instructions in the readme but when I run the following command I get an error (had a bit of a google but can't obviously see the correct syntax for this command)

$ aws configure set plugins.keyring awscli_keyring
usage: aws [options] <command> <subcommand> [parameters]
aws: error: argument command: Invalid choice, valid choices are:
