 ## Generate new GPG signing key:
 ```
-$ export TREZOR_GPG_USER_ID="Satoshi Nakamoto <satoshi@nakamoto.bit>"
+$ export TREZOR_GPG_USER_ID="John Doe <john@doe.bit>"
 ```
 
 ### Create new GPG identity:
 ```
 $ trezor-gpg create > identity.pub                  # create new TREZOR-based GPG identity

 ### Create new subkey for an existing GPG identity:
 ```
 $ gpg2 --list-keys "${TREZOR_GPG_USER_ID}"          # make sure this identity already exists
