# ABOUT
# This script performs a complete installation of Gitlab (master branch).
# Is can be run with one command without needing _any_ user input after that.
# This script only works on Amazon Web Services (AWS).
# The operating system used is Ubuntu 12.04 64bit.

# TODO
# @dosire will send a pull request after this is merged in to change dosire/gitlabhq/non-interactive-aws-install links to gitlabhq/gitlabhq/master and reference this script from installation.md
