A module can be seen as a higher-order organizational unit. It bundles up classes and defined types that contribute to a common management goal (specific system aspects or a piece of software, for example). These manifests are not all that is organized through modules; most modules also bundle files and file templates. There can also be several kinds of Puppet plugins in a module. This section will explain these different parts of a module and show you where they are located. You will also learn about the means of module documentation and how to obtain existing modules for your own use.
