+ *
+ * Apres un apply reussi, Watchtower redemarre core => ce service est
+ * re-instancie => baseline re-aligne sur le registry => check renvoie

+# Demo publique LoreMind
+
+Deploiement d'une instance de demo ephemere pour `loremind-demo.igmlcreation.fr`.
+
+## Principe
+
+Chaque visiteur recoit un environnement isole spawne a la volee, detruit apres
+un court delai d'inactivite. Les donnees ne sont jamais persistees.
+
+Le mode demo (variable d'env `DEMO_MODE=true` sur le core) masque les ecrans
+de configuration qui n'ont pas de sens en vitrine.
+
+## Deploiement
+
+Prerequis :
+- Reseau Traefik existant cote host
+- Images `core` et `brain` pushees au registre
+
+```bash
+cp .env.example .env
+# Ajuster .env
+docker compose -f docker-compose.infra.yml up -d --build
+```
+
+Premier build : 5-10 min. Suivants : incrementaux.
+
+## Mise a jour
+
+```bash
+docker compose -f docker-compose.infra.yml pull
+docker compose -f docker-compose.infra.yml up -d --build
+```
+
+Les sessions en cours sont tuees au redemarrage.
+
+## Observations
+
+- `docker logs loremind-demo-orchestrator -f`
+- `docker ps --filter "name=demo-"`
+
+## Desactiver
+
+```bash
+docker compose -f docker-compose.infra.yml down
+docker ps -q --filter "name=demo-" | xargs -r docker rm -f
+```

+# LoreMindMJ — Installation rapide
+
+Ces scripts installent Docker (si nécessaire), génèrent un `.env` sécurisé
+et lancent la stack. Aucune configuration manuelle requise.
+
+## Windows 10 / 11
+
+Ouvrir **PowerShell** (clic droit → *Exécuter en tant qu'administrateur*) :
+
+```powershell
+iwr https://git.igmlcreation.fr/ietm64/loremind/raw/branch/main/installers/install.ps1 -OutFile $env:TEMP\loremind-install.ps1
+powershell -ExecutionPolicy Bypass -File $env:TEMP\loremind-install.ps1
+```
+
+Le script :
+1. Vérifie / installe **WSL2** (un reboot peut être nécessaire — relancer le script après).
+2. Vérifie / installe **Docker Desktop** via `winget`.
+3. Génère `%LOCALAPPDATA%\LoreMind\.env` avec mots de passe aléatoires.
+4. Lance la stack et ouvre `http://localhost:8081`.
+
+## Linux (Debian / Ubuntu / Fedora / Arch)
+
+```bash
+curl -fsSL https://git.igmlcreation.fr/ietm64/loremind/raw/branch/main/installers/install.sh | bash
+```
+
+Le script :
+1. Installe **Docker** via le script officiel `get.docker.com` si absent.
+2. Ajoute l'utilisateur courant au groupe `docker` (relogin nécessaire la 1ʳᵉ fois).
+3. Installe dans `~/.local/share/loremind`.
+4. Lance la stack et ouvre `http://localhost:8081`.
+
+## Variables disponibles
+
+| Variable          | Défaut                          | Effet                                  |
+|-------------------|---------------------------------|----------------------------------------|
+| `WEB_PORT`        | `8081`                          | Port HTTP de l'UI                      |
+| `INSTALL_DIR`     | `~/.local/share/loremind` (Lin) | Dossier d'installation                 |
+| `NON_INTERACTIVE` | `0`                             | `1` = aucune question, valeurs par défaut |
+
+Exemple Linux non-interactif sur port 9000 :
+
+```bash
+WEB_PORT=9000 NON_INTERACTIVE=1 bash install.sh
+```
+
+## Mises à jour automatiques (Watchtower)
+
+Si vous avez répondu **oui** à la question "Activer les mises à jour auto",
+un container [Watchtower](https://containrrr.dev/watchtower/) est lancé en
+parallèle. Il vérifie chaque nuit à 4h les nouvelles versions de
+`core`, `brain` et `web` sur le registry, télécharge et redémarre les
+conteneurs concernés. **Postgres et MinIO sont volontairement exclus**
+(données persistantes — montée de version à valider manuellement).
+
+### Activer / désactiver après coup
+
+Éditer `.env` dans le dossier d'installation :
+
+```env
+COMPOSE_PROFILES=autoupdate    # active
+COMPOSE_PROFILES=              # desactive
+```
+
+Puis :
+
+```bash
+docker compose up -d            # applique le changement
+docker compose stop watchtower  # si on vient de le desactiver
+```
+
+### Changer l'horaire
+
+`WATCHTOWER_SCHEDULE` dans `.env` accepte la syntaxe
+[cron 6 champs](https://pkg.go.dev/github.com/robfig/cron) (sec min h jour mois j-sem).
+Exemples : `0 0 4 * * *` (4h du matin, défaut), `0 30 3 * * 0` (dimanche 3h30).
+
+### Mode "notification seulement" (sans auto-apply)
+
+Si vous préférez être notifié *sans* que les conteneurs redémarrent
+automatiquement la nuit, éditez `.env` :
+
+```env
+WATCHTOWER_MONITOR_ONLY=true
+```
+
+Puis `docker compose up -d watchtower`. Watchtower continuera à vérifier
+le registry chaque nuit, le badge **MAJ** apparaîtra dans la sidebar de
+l'UI, et un bouton **Mettre à jour maintenant** sera disponible dans
+*Paramètres → Mises à jour*.
+
+### Mise à jour manuelle (à tout moment)
+
+Depuis l'interface : *Paramètres → Mises à jour → Mettre à jour maintenant*.
+
+Ou en CLI :
+
+```bash
+docker compose pull && docker compose up -d
+```
+
+## Désinstallation
+
+```bash
+cd <dossier d'install>
+docker compose down -v   # -v supprime aussi les volumes (données effacées !)
+```
+
+Puis supprimer le dossier d'installation.

+.DESCRIPTION
+  Script d'installation pas-a-pas qui :
+    - Verifie la presence de WSL2 et Docker Desktop ; les installe via winget si absents

+    - Configure le mode Ollama (embarque dans Docker ou Ollama deja installe sur l'hote)
+    - Demarre la stack Docker et ouvre l'application dans le navigateur
+
+  Aucune connexion sortante n'est etablie en dehors :
+    - du depot officiel du projet (fichier docker-compose.yml)
+    - du Docker Hub / registry Docker pour les images
+
+  Le code source de ce script est public et auditable a l'adresse indiquee dans .LINK.
+
