Chris@0: Modules extend your site functionality beyond Drupal core.

Chris@0: WHAT TO PLACE IN THIS DIRECTORY?
Chris@0: --------------------------------
Chris@0: 
Chris@0: Placing downloaded and custom modules in this directory separates downloaded and
Chris@0: custom modules from Drupal core's modules. This allows Drupal core to be updated
Chris@0: without overwriting these files.
Chris@0: 
Chris@0: DOWNLOAD ADDITIONAL MODULES
Chris@0: ---------------------------
Chris@0: 
Chris@0: Contributed modules from the Drupal community may be downloaded at
Chris@0: https://www.drupal.org/project/project_module.

Chris@0: ORGANIZING MODULES IN THIS DIRECTORY
Chris@0: ------------------------------------
Chris@0: 
Chris@0: You may create subdirectories in this directory, to organize your added modules,
Chris@0: without breaking the site. Some common subdirectories include "contrib" for
Chris@0: contributed modules, and "custom" for custom modules. Note that if you move a
Chris@0: module to a subdirectory after it has been enabled, you may need to clear the
Chris@0: Drupal cache so it can be found.
Chris@0: 
Chris@0: There are number of directories that are ignored when looking for modules. These
Chris@0: are 'src', 'lib', 'vendor', 'assets', 'css', 'files', 'images', 'js', 'misc',
Chris@0: 'templates', 'includes', 'fixtures' and 'Drupal'.
Chris@0: 
Chris@0: MULTISITE CONFIGURATION
Chris@0: -----------------------
Chris@0: 
Chris@0: In multisite configurations, modules found in this directory are available to
Chris@0: all sites. You may also put modules in the sites/all/modules directory, and the
Chris@0: versions in sites/all/modules will take precedence over versions of the same
Chris@0: module that are here. Alternatively, the sites/your_site_name/modules directory
Chris@0: pattern may be used to restrict modules to a specific site instance.
