+Ce rôle installe le serveur de HedgeDoc, une application rédaction collaborative en temps-réel utilisant la syntaxe Markdown. 
+
+Notez qu'hormis le présent fichier LISEZMOI.md, tous les fichiers du rôle hedgedoc sont rédigés en anglais afin de suivre les conventions de la communauté Ansible, favoriser sa réutilisation et son amélioration, etc. Libre à vous cependant de faire appel à ce role dans un playbook rédigé principalement en français ou toute autre langue.
+
+Requis
+------
+
+...
+
+Variables du rôle
+-----------------
+
+Plusieurs des valeurs par défaut dans defaults/main.yml doivent être changées soit directement dans defaults/main.yml ou mieux encore en les supplantant ailleurs, par exemple dans votre playbook (voir l'exemple ci-bas).
+
+Dépendances
+------------
+
+Ce rôle Ansible dépend des rôles suivants :
+
+- nodejs
+
+Exemple de playbook
+-------------------
+
+```
+- name: "Déployer un serveur HedgeDoc"
+  hosts: 
+    - all
+  vars:
+    # Supplanter ici les variables du rôle
+    domains: ['votre-vrai-domaine.org']

+    db_host: 'localhost'
+    db_user: "{{ service }}"
