There is a conky to help you out the first time you reboot.
Dwm works – like any other tiling window manager – with keyboard shortcuts.
We give you a general overview. Use the Arch Wiki. We use cups as example to search for drivers for printers. Do not forget the drivers on AUR.
Then we visit the Arch Wiki page on DWM.
We show you where the configuration files are for DWM.
All the settings are in that folder.
The application itself is in /usr/local/bin/dwm.
You can make patches to dwm. They are all online. Some will work. Some will break your system.
We have choosen for the minimal approach. Keep a the number of patches to a minimum and have a stable DWM.
