 ### Hvordan kjøre
 
-`nix run github:Prograrmvarverkstedet/dibbler`
+    nix run github:Programvareverkstedet/dibbler
 
+### Hvordan utvikle?
 
-### Bygge nytt  image
+    python -m venv .venv
+    source .venv/activate
+    pip install -e .
+    cp example-config.ini config.ini
+    dibbler -c config.ini create-db
+    dibbler -c config.ini loop
+
+eller hvis du tolererer nix og postgres:
+
+    direnv allow # eller bare `nix develop`
+    devenv up
+    dibbler create-db
+    dibbler loop
+
+### Bygge 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)
+_(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.**
+Før du bygger imaget burde du lage en `config.ini` fil lokalt som inneholder instillingene dine. **NB: Denne kommer til å ligge i nix storen.**
