Create the package directory that will contain the files and directories with settings.
Copy the settings files and directories to the package directory in the same structure as they should be (or as the files with the same names are) in the sernaInstallationPath.
If you want the ECS Package to be applied together with the installation of Serna, you must name the package directory sernaConfig and place it in the same directory as the Serna installer.
For example, if you want to share the Serna View files (see GUI Layout and Functional Settings (or simply Views)), follow the instructions in How to Create ECS Package with View Files.
