+# Puppet (Masterless) Provisioner
+
+Type: `puppet-masterless`
+
+The masterless Puppet provisioner configures Puppet to run on the machines
+by Packer from local modules and manifest files. Modules and manifests
+can be uploaded from your local machine to the remote machine or can simply
+use remote paths (perhaps obtained using something like the shell provisioner).
+Puppet is run in masterless mode, meaning it never communicates to a Puppet
+master.
+
+<div class="alert alert-info alert-block">
+<strong>Note that Puppet will <em>not</em> be installed automatically
+by this provisioner.</strong> This provisioner expects that Puppet is already
+installed on the machine. It is common practice to use the
+<a href="/docs/provisioners/shell.html">shell provisioner</a> before the
+Puppet provisioner to do this.
+</div>
+
+## Basic Example
+
+The example below is fully functional and expects the configured manifest
+file to exist relative to your working directory:
+
+<pre class="prettyprint">
+{
+  "type": "puppet-masterless",
+  "manifest_file": "site.pp"
+}
+</pre>
+
+## Configuration Reference
+
+The reference of available configuration options is listed below.
+
+Required parameters:
+
+* `manifest_file` (string) - The manifest file for Puppet to use in order
+  to compile and run a catalog. This file must exist on your local system
+  and will be uploaded to the remote machine.
+
+Optional parameters:
+
+* `execute_command` (string) - The command used to execute Puppet. This has
+  various [configuration template variables](/docs/templates/configuration-templates.html)
+  available. See below for more information.
+
+* `module_paths` (array of strings) - This is an array of paths to module
+  directories on your local filesystem. These will be uploaded to the remote
+  machine. By default, this is empty.
+
+* `prevent_sudo` (boolean) - By default, the configured commands that are
+  executed to run Puppet are executed with `sudo`. If this is true,
+  then the sudo will be omitted.
+
+* `staging_directory` (string) - This is the directory where all the configuration
+  of Puppet by Packer will be placed. By default this is "/tmp/packer-puppet-masterless".
+  This directory doesn't need to exist but must have proper permissions so that
+  the SSH user that Packer uses is able to create directories and write into
+  this folder. If the permissions are not correct, use a shell provisioner
+  prior to this to configure it properly.
+
+## Execute Command
+
+By default, Packer uses the following command (broken across multiple lines
+for readability) to execute Puppet:
+
+```
+{{if .Sudo}sudo {{end}}puppet apply \
+  --verbose \
+  --modulepath='{{.ModulePath}}' \
+  {{.ManifestFile}}
+```
+
+This command can be customized using the `execute_command` configuration.
+As you can see from the default value above, the value of this configuration
+can contain various template variables, defined below:
+
+* `ManifestFile` - The path on the remote machine to the manifest file
+  for Puppet to use.
+* `ModulePath` - The paths to the module directories.
+* `Sudo` - A boolean of whether to `sudo` the command or not, depending on
+  the value of the `prevent_sudo` configuration.
