A port is built in the working directory work/ inside the ports directory.
It will allow you to upgrade mports and install mports much easier.
This is quite innovative compared to the Free BSD maybe it works as a package approach, but other projects like Open BSD have been doing something similar for quite some time.
Currently, all commiters have access to add and modify mports.
It contains hundreds of ported software applications ready to use on Midnight BSD.
mports simplifies installing software packages on your desktop system.
