In the Netherlands municipalities have been collaborating for years already to build an open source ecosystem: https://commonground.nl/

We have 342 municipalities, all buying the same apps (from 3 or 4 vendors) to deliver basic services to their citizens. Common Ground aims to replace all of those with open source solutions.

Hey, I would love to contribute to this project. Is there a list of repo's I can take a look at and contribute?

I see some communities, seems like each community has their own setup, some of them have github links.
