+## Instalowanie
+
+Jest opcja żeby zainstalowało wszystko automatycznie, ale jest to wolne i mało optymalne (jak wszystko co jest "automatyczne"). Ale robi się samo:
+
+Ten skrypt stworzy plik ~/.config/nix/nix.conf i folder ~/.nix-portable gdzie będą przechowywane wszystkie potrzebne programy itp. - jak usuniesz to będzie trzeba na nowo pobrać
+
+```sh
+# Potrzebujesz `curl`, 1.3G wolnego miejsca i internet który to pobierze
+./bin/install-all
+```
+
+Ten skrypt pobiera dużo rzeczy, które prawdopodobnie twój komputer gdzieś ma, ale każdy system jest inny, więc tak jest prościej i działa wszędzie. Jeśli potrzebujesz zaoszczędzić miejsca to postępuj według instrukcji swojej dystrybucji.
