 EDB-system for PVVVV
 
+## Hva er dette?
+
+Dibbler er et system laget av PVVere for PVVere for å byttelåne både matvarer og godis.
+Det er designet for en gammeldags VT terminal, og er laget for å være enkelt både å bruke og å hacke på.
+
+Programmet er skrevet i Python, og bruker en sql database for å lagre data.
+
+Samlespleiseboden er satt opp slik at folk kjøper inn varer, og får dibblerkreditt, og så kan man bruke
+denne kreditten til å kjøpe ut andre varer. Det er ikke noen form for authentisering, så hele systemet er basert på tillit.
+Det er anbefalt å koble en barkodeleser til systemet for å gjøre det enklere å både legge til og kjøpe varer.
+
+## Kom i gang
+
+Installer python, og lag og aktiver et venv. Installer så avhengighetene med `pip install`.
+
+Deretter kan du kjøre programmet med
+
+```console
+python -m dibbler -c example-config.ini create-db
+python -m dibbler -c example-config.ini loop
+```
+
