+
+You can set config values two ways, via --section, --key, --value or by command arguments.
+
+To use --section, --key, --value, simply supply those options. You can only set one setting this way, and you cannot
+append to arrays.
+
+To use arguments, supply one or more arguments in the following format: Section.config_setting_name=\"value\"
+'Section' is the name of the section, 'config_setting_name' the name of the setting and 'value' is the value.
+NOTE: 'value' must be JSON encoded, so Section.config_setting_name=\"value\" would work but
+Section.config_setting_name=value would not.
+
+To append to an array setting, supply an argument like this: Section.config_setting_name[]=\"value to append\"
+
+To reset an array setting, supply an argument like this: Section.config_setting_name=[]
+Resetting an array will not work if the array has default values in global.ini.php (such as, [log] log_writers).
+In this case the values in global.ini.php will be used, since there is no way to explicitly set an
+array setting to empty in INI config.
+
+Use the --piwik-domain option to specify which instance to modify.
