+# Core Configuration
+
+There are a few configuration settings that affect Packer globally by
+configuring the core of Packer. These settings all reasonable defaults, so
+you generally don't have to worry about it until you want to tweak
+a configuration. If you're just getting started with Packer, don't worry
+about core configuration for now.
+
+By default, Packer looks for the core configuration to be in `~/.packerconfig`.
+This file is a JSON file. If it doesn't exist, then Packer ignores it
+and just uses the default configuration.
+
+The location of the core configuration file can be modified by setting
+the `PACKER_CONFIG` environmental variable to be the path to another file.
+
+## Configuration Reference
+
+Below is the list of all available configuration parameters for the core
+configuration file. None of these are required, since all have sane defaults.
+
+* `plugin_min_port` and `plugin_max_port` (int) - These are the minimum and
+  maximum ports that Packer uses for communication with plugins, since
+  plugin communication happens over TCP connections on your local host.
+  By default these are 10,000 and 25,000, respectively. Be sure to set a fairly
+  wide range here, since Packer can easily use over 25 ports on a single run.
+
+* `builders`, `commands`, and `provisioners` are objects that are used to
+  install plugins. The details of how exactly these are set is covered
+  in more detail in the [installing plugins documentation page](/docs/extend/plugins.html).
