Place downloaded and custom installation profiles in this directory to ensure separation from Drupal core profiles and to facilitate safe, self-contained code updates. In multisite configuration, installation profiles found in this directory are available to all sites during their initial site installation. Shared common profiles may also be kept in the sites/all/profiles directory and will take precedence over profiles in this directory. Alternatively, the sites/your_site_name/profiles directory pattern may be used to restrict a profile's availability to a specific site instance. Additionally, modules and themes may be placed inside subdirectories in a specific installation profile such as profiles/your_site_profile/modules and profiles/your_site_profile/themes respectively to restrict their usage to only sites that were installed with that specific profile. Refer to the "Installation Profiles" section of the README.txt in the Drupal root directory for further information.
