...Our mainline desktop Peppermint ships with the desktop environment xfce with the thunar file manager set as default. Peppermint comes with nearly nothing installed other than, the core packages needed to run the system and you have the choice to which packages should best fit your build.
We do use the common process of continuous delivery, and we are based on the Debian/Devuan repositories.
Please post any questions about PeppermintOS to our Community Forum page: https://sourceforge.net/p/peppermintos/pepos/ and do our best to assist you.
