+## Files organization
+The nix config files are separated in the following folders:
+- `packages` for the self-defined packages that have to be added to the system (i.e. self patched versions of softwares)
+- `modules` for self-defined modules
+- `machines/xxx` one folder xxx for the specific configuration every machine using this configuration of nixos
+- `profiles/xxx` one folder for a set of applications/modules/things i want to get applied
