It requires you use an apt-compatible OS (Debian, Ubuntu).
It installs basic packages such as curl and git, then installs
- Ruby 1.9.2 (& sets it as the default)
And it sets up an example dev and test database (which are actually the
dev and test database for the pcmag project) and runs
in the project directory.
But you could have figured all of this out by reading playbook.yml just as quickly as you read this.
