Quick reference to setting up puppet.
First install puppet:
wget http://apt.puppetlabs.com/puppetlabs-release-precise.deb
sudo dpkg -i puppetlabs-release-precise.deb
sudo apt-get update
sudo apt-get install puppet-common
Now git clone your puppet repo into /etc/puppet or use a puppetmaster.
*Remember to sudo su so all the file permissions are correct`.
Now include modules in your /etc/puppet/ and config your site.pp.
Finally: use the Module and Core Types cheat sheets.
