FAQs
Where can I find the project roadmap and the planned features?
We want to make a formal collaboration agreement. Are there any templates we can use?

Yes, we have templates to formalize collaboration agreements. Please contact us.

What is Decidim's trademark policy?

Decidim and the Decidim logo are registered by the Association, they cannot be used as a commercial product nor cannot be sold. If used, the credit has to be referenced to the project. You can read more about this in our Trademark policy.

Can I join the Metadecidim community even if I don't live in Barcelona?

Of course you can. People do so through participatory processes, debates, translations, etc. that you might find in Metadecidim. Decidim was born in Barcelona and that is why there is a strong territorial bond with this city, but above all, it's a project for the commons.
