 ## Prérequis
 
+- Docker et docker compose installés
+- Nginx utilisé via le service `nginx` de l'orchestrateur
+
 ## Installation locale
 
+- Cloner le dépôt et se placer à la racine
+- Vérifier la présence des répertoires `modules/` et `projects/` avec `conf/`, `data/`, `logs/`, `scripts/`
+- Vérifier la disponibilité des images taggées `:dev` (en cours de création) ou utiliser des tags stables le cas échéant
+
 ## Démarrage
 
+- Démarrer la stack applicative : `docker compose up -d`
+- Démarrer la stack de monitoring (Loki/Promtail/Grafana) si souhaité : `docker compose -f log-monitoring.yml up -d`
+- Accéder aux services via Nginx :
+  - IHM: `http://localhost/`
+  - Blindbit: `http://localhost/blindbit/`
+  - SDK Storage: `http://localhost/sdk_storage/`
+  - Relais HTTP: `http://localhost/relay1/`, `/relay2/`, `/relay3/`
+  - Relais WebSocket: `ws://localhost/relay1/ws/` (idem `relay2`, `relay3`)
+  - Signer WS: `ws://localhost/signer/ws/`; HTTP: `http://localhost/signer/`
+  - Coffre front: `http://localhost/coffre/`
+
 ## Commandes utiles
 
+- Mettre à jour les images: `docker compose pull`
+- Voir les logs Nginx: `tail -f log/nginx/4nk_node.access.log`
+- Voir les logs des services (montés): `tail -f modules/<service>/logs/*`
+- Logs Promtail/Loki/Grafana: voir `log/` et `log-monitoring.yml`
+
 ## Dépannage
+
+- Vérifier les hostnames Docker internes (DNS du réseau `4nk_network`): voir `docker-compose.yml`
+- Les tags `:dev` sont en cours de création; en cas d’indisponibilité, utiliser des tags stables temporaires
+- Conf Tor: `modules/tor/conf/tor.conf` est montée si l'image Tor supporte `/etc/tor/torrc`
