create complains that the repo I'm creating doesn't exist (?!)

[Igor Santos]

$ github create test
ERROR: myuser/test.git doesn't exist. Did you enter it correctly?
fatal: The remote end hung up unexpectedly

Am I missing something or this command would be used to create the repository into github, and then create a README and commit and push it?
I needed to come to github and create the repository in the browser, and then that command worked.
