Redmine provides plugin authors with an integrated configuration system in order to simplify the management of configuration values:

Plugin settings are only available to Redmine users with administrator privileges. For these users, a summary of all plugins is available at http://localhost:3000/admin/plugins.

If a plugin has been configured to provide an administrator with a settings view, a Configure link will be available.

The information that is displayed for each plugin in the list is pulled from the name, author, author_url, description, url, and version attributes that were provided to the Redmine::Plugin.register block in each plugin's init.rb file.
