-# Study-M1-PDS
+# Master 1 - Projet de Spécialité
 
-(Université) - Projet De Spécialité
+Ce projet consiste en une application Android permettant à des enseignants de créer des session de cours où un ensemble
+d'élève est assigné à des tâches de sujet différent qui peuvent être validé collaborativement.
+
+Il est possible d'utiliser le QR code des cartes étudiantes afin de substituer l'identifiant d'un étudiant et de
+pouvoir valider rapidement les tâches d'un élève.
+
+# Build
+
+1. Cloner le projet `git clone https://git.faraphel.fr/study-faraphel/M1-PDS`
+2. Ouvrer le dans Android Studio ou Intellij IDEA
