+# Squelette du TP
+
+## Utilisation
+
+Pour utiliser ce tp vous devez :
+
+1. le forker via le lien fork ci-dessus.
+2. Votre repository doit être **privé**. Vous devez le partager avec votre encadrant de TP.
+3. vous obtiendrez un nouveau lien : par exemple git@gitlab.istic.univ-rennes1.fr:monpseudo/....
+4. Dans le **workspace d'eclipse** faites `git clone git@gitlab.istic.univ-rennes1.fr:monpseudo/...` avec l'url précédente.
+5. Ouvrez le workspace dans eclipse. 
+6. Utilisez Import> "Existing Maven Projects".
+7. Selectionnez le projet et validez.
+
+Vous devriez avoir une version du projet dans votre propre compte gitlab.
+
+Vous pouvez le partager avec votre binome et l'encadrant de TP.
+
+
+## Rapport 
+
+Votre rapport doit être écrit ici en markdown.
+
+Vous trouverez la syntaxe de markdown ici : https://docs.gitlab.com/ee/user/markdown.html
+
+Placez vos images dans le répertoire images si nécessaire.
+
+
+
+## Faire des diagrammes 
+
+En particulier vous pouvez utiliser [mermaid](https://mermaidjs.github.io/) :
+
+
+
+```mermaid
+sequenceDiagram
+    participant Alice
+    participant Bob
+    Alice->John: Hello John, how are you?
+    loop Healthcheck
+        John->John: Fight against hypochondria
+    end
+    Note right of John: Rational thoughts <br/>prevail...
+    John-->Alice: Great!
+    John->Bob: How about you?
+    Bob-->John: Jolly good!
+```
+
+## Insérer du code 
+
+Insérer du `code` :
+
+```java
+public interface ClientHandler {
+    public void handle();
+}
+```
