+# Gestion Let's encrypt
+
+## Fonctionnement du service application
+
+Ce service gère le téléchargement et la mise à disposition des certificats Let's encrypt.
+
+Le certificat doit être disponible avant l'installation de la machine de destination.
+C'est pourquoi ce le certificat est téléchargement grâce au défi DNS-1.
+
+Il faut donc installer certbot + python3-certbot-dns-xxx (sur une Fedora), par exemple pour OVH "python3-certbot-dns-ovh".
+
+Attention, en utilisant ce service vous acceptez les conditions d'utilisation de Let's Encrypt !
+
+## Utiliser Let's encrypt dans une machine
+
+Dans applicationservice.yml ajouter la dépendance "letsencrypt".
+
+Sur la machine installer Certb
+
+## Configurer Let's encrypt
+
+```
+rougail.letsencrypt.domain_names": ["nom de domaine"],
