+# Personnalisation
+Vous pouvez modifier les variables d'environnement afin de modifier le logo et le titre de votre installation.
+Ce logiciel étant libre et sous la licence GNU Affero V3 vous pouvez bien entendu le modifier à volonté. Voici donc un guide concernant le titre et le logo.
+
+Modifiez le fichier `src/environment.prod.ts`, et remplacez le contenu des variables `appTitle` (un texte, pas forcément un seul mot) et `appLogo` (une URL absolue ou relative d'image)
+ Et voilà!
+ 
+Quand vous builderez votre app, vous verrez ces valeurs dans la barre titre, incluses par le composant HeaderComponent automatiquement.
+
+Vous pouvez modifier les valeurs dans le fichier  `src/environment.ts` pour voir ce que cela donne en environnement de développement en lancant l'app avec `npm start` ou `yarn start`.
+
+#Customization
+Change the content of the file `src/environment.prod.ts`, and the content of the vars `appTitle` (any text) and `appLogo` (any picture URL, relative or absolute) .
+ And voilà!
