I was reading an article about a new DE which is already available in Arch, Manjaro(spin) and probably other arch-based distros too, that eventually led me to this other article from the Manjaro wiki https://wiki.manjaro.org/index.php/Install_Desktop_Environments though instructions are for Manjaro mainly and likely applicable to arch and the different arch-based distros out there, I think it is possible too to adapt them, so they can be used in any non arch-based distros as well. Also, the article contains a few good tips, tricks as well as some valuable dos and don'ts about using different DEs.
