+ * @file
+ * Configuration file for multi-site support and directory aliasing feature.
+ *
+ * This file is required for multi-site support and also allows you to define a
+ * set of aliases that map hostnames, ports, and pathnames to configuration
+ * directories in the sites directory. These aliases are loaded prior to
+ * scanning for directories, and they are exempt from the normal discovery
+ * rules. See default.settings.php to view how Drupal discovers the
+ * configuration directory when no alias is found.
+ *
+ * Aliases are useful on development servers, where the domain name may not be
+ * the same as the domain of the live server. Since Drupal stores file paths in
+ * the database (files, system table, etc.) this will ensure the paths are
+ * correct when the site is deployed to a live server.
+ *
+ * To activate this feature, copy and rename it such that its path plus
+ * filename is 'sites/sites.php'.
+ *
+ * Aliases are defined in an associative array named $sites. The array is
+ * written in the format: '<port>.<domain>.<path>' => 'directory'. As an
+ * example, to map https://www.drupal.org:8080/mysite/test to the configuration
+ * directory sites/example.com, the array should be defined as:
+ * @code
+ * $sites = [
+ *   '8080.www.drupal.org.mysite.test' => 'example.com',
+ * ];
+ * @endcode
+ * The URL, https://www.drupal.org:8080/mysite/test/, could be a symbolic link
+ * or an Apache Alias directive that points to the Drupal root containing
+ * index.php. An alias could also be created for a subdomain. See the
+ * @link https://www.drupal.org/documentation/install online Drupal installation guide @endlink
+ * for more information on setting up domains, subdomains, and subdirectories.
+ *
+ * The following examples look for a site configuration in sites/example.com:
+ * @code
+ * URL: http://dev.drupal.org
+ * $sites['dev.drupal.org'] = 'example.com';
+ *
+ * URL: http://localhost/example
+ * $sites['localhost.example'] = 'example.com';
+ *
+ * URL: http://localhost:8080/example
+ * $sites['8080.localhost.example'] = 'example.com';
+ *
+ * URL: https://www.drupal.org:8080/mysite/test/
+ * $sites['8080.www.drupal.org.mysite.test'] = 'example.com';
+ * @endcode
+ *
+ * @see default.settings.php
+ * @see \Drupal\Core\DrupalKernel::getSitePath()
+ * @see https://www.drupal.org/documentation/install/multi-site

+// Copy this file to local.sites.php on your local to use it. This file has a
+// built in convention to use http://sdssgryphon-SITENAME.test. You can change
+// the convention in the below code to match your local environment setup.
+
+// Use similar conventions as live sites for local.
+// Underscores "_" in the site name/alias become dashes "-" in local URL's.
+// Double underscores "__" become dots ".".
+// E.g., carbon_removal will be carbon-removal.
+// When setting local domain use sdssgryphon-SITENAME.test or update the below
+// code to use own conventions.
+// E.g., carbon_removal becomes sdssgryphon-carbon-removal.test
