Manjaro LXDE Community Edition
The Manjaro LXDE Community Edition includes several applications and default configurations which make it really user friendly.
You should also take a look at this topic which has some information about the manjaro lxde edition: https://forum.manjaro.org/t/tips-tricks-and-general-info-for-manjaro-lxde-community-edition/24466
Manjaro is based on arch, so you can follow the instructions from the arch page. Install also the package **manjaro-lxde-settings** if you want to use the default configurations of the manjaro lxde edition (you will need to create a new user or copy the contents from /etc/skel, afterwards).
