+# Dibbler
+
+EDB-system for PVVVV
+
+## Nix
+### Hvordan kjøre
+
+`nix run github:Prograrmvarverkstedet/dibbler`
+
+
+### Bygge nytt  image
+
+For å bygge et image trenger du en builder som takler å bygge for arkitekturen du skal lage et image for.
+
+(Eller be til gudene om at cross compile funker)
+
+Flaket exposer en modul som autologger inn med en bruker som automatisk kjører dibbler, og setter opp et minimalistisk miljø.
+
+Før du bygger imaget burde du endre conf.py lokalt til å inneholde instillingene dine. **NB: Denne kommer til å ligge i nix storen.**
+
+Du kan også endre hvilken conf.py som blir brukt direkte i pakken eller i modulen.
+
+Se eksempelet for hvordan skrot er satt opp i flake.nix
+
+### Bygge image for skrot
+Skrot har et image definert i flake.nix:
+
+1. endre conf.py
+2. `nix build .#images.skrot`
+3. ???
+4. non-profit
