+This directory is reserved for core module files. Custom or contributed
+modules should be placed in their own subdirectory of the sites/all/modules
+directory. For multisite installations, they can also be placed in a subdirectory
+under /sites/{sitename}/modules/, where {sitename} is the name of your site
+(e.g., www.example.com). This will allow you to more easily update Drupal core files.
