How to install Puppet

The installation of Puppet on the main Linux distributions is quite easy, being its packages provided directly in the main repositories or in well-know extra ones.
The versions you currently find by default are generally of the 0.2x series, so if you need to install Puppet 2.6.x you have to add further specific repos with the latest packages.

In order to use the Example42 Puppet modules git is reccomended too. You can easily find its packages on all the Linux distros.
