 This repository contains code to run Deuxfleur's infrastructure on NixOS.
 
-It sets up the following:
+## Our abstraction stack
 
-- A Wireguard mesh between all nodes
-- Consul, with TLS
-- Nomad, with TLS
+We try to build a generic abstraction stack between our different resources (CPU, RAM, disk, etc.) and our services (Chat, Storage, etc.), we develop our own tools when needed.
+
+Our first abstraction level is the NixOS level, which installs a bunch of standard components:
+
+  * **Wireguard:** provides encrypted communication between remote nodes
+  * **Nomad:** schedule containers and handle their lifecycle
+  * **Consul:** distributed key value store + lock + service discovery
+  * **Docker:** package, distribute and isolate applications
+  
+Then, inside our Nomad+Consul orchestrator, we deploy a number of base services:
+
+  * **[Garage](https://git.deuxfleurs.fr/Deuxfleurs/garage/):** S3-compatible lightweight object store for self-hosted geo-distributed deployments (we also have a legacy glusterfs cluster)
+  * **[DiploNAT](https://git.deuxfleurs.fr/Deuxfleurs/diplonat):** network automation (firewalling, upnp igd)
+  * **[Bottin](https://git.deuxfleurs.fr/Deuxfleurs/bottin):** authentication and authorization (LDAP protocol, consul backend)
+  * **[Guichet](https://git.deuxfleurs.fr/Deuxfleurs/guichet):** a dashboard for our users and administrators
+  * **Stolon + PostgreSQL:** distributed relational database
+  * **Prometheus + Grafana:** monitoring
+
+Some services we provide based on this abstraction:
+
+  * **Websites:** Garage (static) + fediverse blog (Plume)
+  * **Chat:** Synapse + Element Web (Matrix protocol)
+  * **Email:** Postfix SMTP + Dovecot IMAP + opendkim DKIM + Sogo webmail  | Alps webmail (experimental)
+  * **Visioconference:** Jitsi
+  * **Collaboration:** CryptPad
+
+As a generic abstraction is provided, deploying new services should be easy.
