These are instructions for setting up git to authenticate with GitHub when you have 2-factor authentication set up. This authentication should be inherited by any GUI client you are using. These are intentionally brief instructions, with links to more detail in the appropriate places.

1. Download and install the git command-line client (if required).

2. Open the git bash window and introduce yourself to git (if required):

   git config --global user.name 'Firstname Lastname'
   git config --global user.email '[email protected]'

Howto: Install Alpine Linux 3.3 on VirtualBox OSX

• Latest Standard ISO version x86_64 is recommended (http://alpinelinux.org/downloads/)
• Create new VM ("Linux 2.6 / 3.x / 4.x (64-bit)")
• 1 CPU w/ 512BM RAM and 1 GB default (VDI) disk is more than sufficient
• Default networking (NAT)
• Boot and add Alpine ISO as attached virtual install media
• Default root password is blank (though note - ssh PermitRootLogin defaults to disallow blank passwords and: prohibit-password; switch to yes for Host ssh)
• Run setup-alpine
• Defaults are fine, but you do want "sys" disk setup to sda, y to confirm
