+# Salt Masterless Provisioner
+
+Type: `salt-masterless`
+
+The `salt-masterless` provisioner provisions machines built by Packer using
+[Salt](http://saltstack.com/) states, without connecting to a Salt master.
+
+## Basic Example
+
+The example below is fully functional.
+
+<pre class="prettyprint">
+{
+    "type": "salt-masterless",
+    "local_state_tree": "/Users/me/salt"
+}
+</pre>
+
+## Configuration Reference
+
+The reference of available configuration options is listed below. The only required argument is the path to your local salt state tree.
+
+Required:
+
+* `local_state_tree` (string) - The path to your local
+  [state tree](http://docs.saltstack.com/ref/states/highstate.html#the-salt-state-tree).
+  This will be uploaded to the `/srv/salt` on the remote, and removed before
+  shutdown.
+
+Optional:
+
+* `skip_bootstrap` (boolean) - By default the salt provisioner runs
+  [salt bootstrap](https://github.com/saltstack/salt-bootstrap) to install
+  salt. Set this to true to skip this step.
+
+* `boostrap_args` (string) - Arguments to send to the bootstrap script. Usage
+  is somewhat documented on [github](https://github.com/saltstack/salt-bootstrap),
+  but the [script itself](https://github.com/saltstack/salt-bootstrap/blob/develop/bootstrap-salt.sh)
+  has more detailed usage instructions. By default, no arguments are sent to
+  the script.
+
+* `temp_config_dir` (string) - Where your local state tree will be copied
+  before moving to the `/srv/salt` directory. Default is `/tmp/salt`.
+
+* `minion_config` (string) - The path to your local
+  [minion config](http://docs.saltstack.com/topics/configuration.html).
+  This will be uploaded to the `/etc/salt` on the remote.
