•Built-in settings - these settings are added during the installation process and cannot be modified. They are used to set the built-in modules, same as other features of the whole CMS. You can configure them in Site Manager -> Settings; please refer to the Configuring settings topic for more details.
•Custom settings - the user can create their own settings for modules and other functionality they added to the CMS. This can be done in Site Manager -> Development -> Custom settings; please refer to the Adding custom settings and Managing custom settings topics for more details. If you need to configure custom settings, you can do it the same way like with the built-in settings, i.e. in Site Manager -> Settings; please refer to the Configuring settings topic for more details.
These settings are used for low-level configuration of the CMS system. More details can be found in Appendix B - Web.config parameters.
