typing 'rails console' doesn't start?

I typed this:

>rails console

and got this:

Usage:
  rails new APP_PATH [options]

Options:
      [--skip-gemfile]        # Don't create a Gemfile
  -d, [--database=DATABASE]   # Preconfigure for selected database (options: mysql/oracle/postgresql/sqlite3/frontbase/ibm_db)
                              # Default: sqlite3
..
..
.

I'm following along the rails tutorial and got stuck on this.

I have rails 3.0 installed.
