How it works

Armada is a chat app with nothing at the center of it. There is no server that holds your community, no account to be locked out of, and no operator who can read what you send. This section explains what replaces each of those.

What goes here

Keys, not accounts — what a Nostr key is, what it signs, and what it costs you to lose one.
Relays — where events actually live, why there is more than one, and what a relay can and cannot see.
Communities — Concord: encrypted streams that need no host, and how membership, invites and rekeying work without one.
Servers — the other mode: NIP-29 relay-hosted servers, for operators who want to run something.
Voice and video — how calls get set up, and what the broker in the middle is trusted with.
Your devices — one key across web, desktop, Android and iPhone, and what syncs between them.
