Now, from the virtual machine (connect with "vagrant ssh" if vagrant didn't
log you in already), you can start Studio & LMS with the following commands:

- Learning management system (LMS):
    $ rake lms[cms.dev,0.0.0.0:8000]

    =>  http://192.168.20.40:8000/

- Studio:
    $ rake cms[dev,0.0.0.0:8001]

    => http://192.168.20.40:8001/


See the README for details.
