+STORING CONFIG FILES OUTSIDE THE MINIFY DIRECTORY
+
+It is possible to store config files (config.php, config-test.php, groupsConfig.php)
+in a custom directory outside the Minify directory. This is useful if you wish to
+include Minify as an external dependency inside another project via SVN external or
+Git submodule inclusion.
+
+For example, let's assume you have a Minify directory "min" in your site root. Then
+you could create a new directory called "min-configs" in the site root. Copy any
+config files you wish to modify to "min-configs", and modify as desired.
+
+Then create a new file, for example "min.php" in your site root. The contents of
+this file could look like this:
+
+<?php
+define('MINIFY_CUSTOM_CONFIG_DIR', dirname(__FILE__) . '/min-configs');
+
+include_once 'min/index.php';
+
+You would then reference min.php in your JS and CSS links instead of min/index.php.
+
+This method will also affect those using the Minify_getUri() function. You will need
+to add options to calls to that function, e.g.:
+
+<?php
+require $_SERVER['DOCUMENT_ROOT'] . '/min/utils.php';
+
+$jsUri = Minify_getUri('//js/file.js', array('minAppUri' => '/min.php'));
+echo "<script src='{$jsUri}'></script>";
