+## Bonjour et bienvenue sur le dépôt du projet LIVRE LAND ! 👋
+
+*******
+
+### Sommaire 
+ 1. [Accessibilité](#acces)
+ 2. [Progression](#progression)
+ 3. [Présentation du projet](#presentation)
+ 4. [Architecture](#architecture)
+ 5. [Contenu](#contenu)
+ 6. [Auteurs](#auteurs)
+
+*******
+
+<div id='acces'/> 
+
+Pour accéder au code de l'application, vous pouvez cloner la branche `master` du dépôt Code#0 et ouvrir celle-ci dans `Microsoft Visual Studio` par exemple.    
+  
+Disponible sur :    
+![](https://img.shields.io/badge/Android-3DDC84?style=for-the-badge&logo=android&logoColor=white)
+![](https://img.shields.io/badge/iOS-000000?style=for-the-badge&logo=ios&logoColor=white)  
+  
+> **Warning**: L'application est fonctionnelle sous Windows et Android mais n'a pas été testée sous IOS.   
+
+- Dans la branche **Master**, vous retrouverez l'intégralité de l'application avec les fonctionnalités du `TP2` ainsi que le scan de code-barres.  
+
+- Dans la branche **TP3**, vous retrouverez l'implémentation du `MVVM Community Toolkit` dans notre application.  
+
+*******
+
+<div id='progression'/>
+
+## 🚧  __EN PROGRESSION__
+
+### Étape 1 : Développement des vues en XAML  
+- Intégralité des pages proposées sur la page d'accueil développées
+- Mode clair & Mode sombre disponibles (pas très esthétique)
+- Utilisable en mode portrait ou mode paysage  
+- Exploitation des Styles et des Content View réutilisables  
+- Mise à disposition de quelques données dans un Stub pour la présentation des vues  
+- View Model non utilisés et fonctionnalités pas toutes mises en place (seulement les vues)
+- Navigation généralement utilisable mais pas parfaitement codée  
+
+---
+
+### Étape 2 : Personnal MVVM Toolkit
+
+La création de ce `Toolkit Personnel` a pour but de faciliter le développement de l'application en fournissant un ensemble de fonctionnalités et de composants réutilisables. De plus, à l'aide d'une classe comme `RelayCommand`, notre objectif est de ne pas inclure dans nos ViewModels une dépendance avec les Commands de .NET MAUI.  
+  
+Nous pouvons représenter la structure de notre toolkit avec le diagramme suivant :  
+
+```mermaid
+classDiagram
+direction LR
+class INotifyPropertyChanged {
+    <<interface>>
+}
+
+class ObservableObject{
+    +PropertyChanged: event PropertyChangedEventHandler?;
+    #OnPropertyChanged (string PropertyName = null) : void
+    #SetProperty<T> (T member, T value, Action<T> action, string propertyName = null) : void
+    #SetProperty<T> (ref T member, T value, string propertyName = null) : void
+}
+
+class BaseViewModel{
+    +Model: TModel;
+    -model: TModel;
+    +BaseViewModel(TModel model)
+    +BaseViewModel() : this(default)
+}
+
+class ICommand{
+    <<interface>>
+}
+
+class RelayCommand{
+    +CanExecuteChanged: event EventHandler?;
+    +CanExecute (object? parameter) : bool
+    +Execute (object? parameter) : void
+    +RefreshCommand() : void
+} 
+
+ObservableObject ..|> INotifyPropertyChanged
+BaseViewModel --|> ObservableObject
+RelayCommand ..|> ICommand
+```
+  
+Cette structure est une version remplaçant pour le moment le `Community Toolkit` mis en place par Microsoft qui permet aussi de supprimer beaucoup de code inutile en remplaçant celui-ci par des annotations et des classes partielles.  
+
+---
+
+### Étape 3 : MVVM  
+
+Nous utilisons au sein de notre projet le **patron d'architecture MVVM** avec les ViewModels Wrapping et Applicatives.  
+  
+Nous retrouvons donc les 3 grandes parties du patron :  
+  
+- **Model** :  
+Le `Model` représente la `logique métier`. Il est écrit en `C#` et est adpaté pour diifférentes applications.  
+  
+- **View** :  
+Les `Vues` sont écrites en `XAML` et représentent l'interface utilisateur avec les vues de l'application. Le `Data Binding` est utilisé entre les propriétés du XAML et celles des ViewModels. Enfin, des évènements sont déclenchés à partir de certains composants des vues.
+  
+- **ViewModel** :
+Les `ViewModels` sont écrits en `C#` et sont divisables en deux grandes catégories :  
+    * Les **Wrapping ViewModel** encapsulent les données du modèle et exposent des propriétés et des commandes nécessaires à la vue pour interagir avec le modèle.   
+    * Les **Applicative ViewModel** peuvent inclure une logique métier spécifique et des propriétés calculées, elles peuvent également exposer des commandes pour effectuer des actions spécifiques liées à la vue.  
+  
+Le schéma suivant montre bien les relations entre les grandes parties du `patron MVVM` :  
+  
+![Schema_MVVM](documentation/schema_mvvm.png)
+ 
+Le **diagramme de classes** pouvant être extrèmement grand à cause des multiples classes au sein de notre projet, j'ai décidé de représenter une partie de celui-ci qui pourrait se répéter pour toutes les autres parties. L'objectif principal étant de comprendre comment fonctionne le **modèle MVVM** et comment les classes intéragissent entre elles, j'ai choisi de faire mon exemple avec la partie des livres qui est la plus générale du sujet.

+
+## Fonctionnalités
+
+**TP2 - Base** : 
+- [x] Page d'accueil  
+- [x] Affichage des livres de l'utilisateur : afficher tous les livres de l'utilisateur dans la vue BooksPage et permettre la sélection d'un livre et la navigation vers la page BookPage  
+    * seule la note n'est pas encore affichée sous la forme d'étoiles (commencée dans `star-notation-22-10`)
+- [x] Filtrage par auteur et par date de publication : afficher dans la vue de filtrage (FilterPage)  
+  
+**TP2 - Ajouts** :  
+- [x] Changer le statut de lecture d'un livre  
+- [x] Ajouter un livre aux favoris  
+- [x] Filtrer les livres par Auteur, Date de publication, Note 
+    * le filtrage fonctionne, au deuxième clique sur une date par exemple une fois une première date visitée, je remarque des soucis avec de temps à autre une exception
+- [x] Ajouter un livre à sa collection en saisissant l'ISBN
+- [x] Supprimer un livre  
+- [x] Prêter un livre (et ajouter un contact si besoin)  
+    * la page avec les contacts n'est pas esthétiquement très réussie
+- [x] Consulter la liste des livres prêtés
+    * j'ai fait le choix de n'afficher que les livres _actuellement_ prêtés ou empruntés  
+  
+_Erreurs rencontrées_ :
+* L'ajout en favoris fonctionne, cependant il m'ait arrivé lorque je choisissais à partir de la page BooksPage d'ajouter un livre qui ne se trouve pas sur la première page, que celui-ci supprime souvent tous les livres déjà en favoris.  
+* J'ai également eu à certains moments des problèmes avec l'accession à la page de détails et une double page qui s'ouvrait; dans ce cas je relance généralement l'application.  
+  
+**TP3** :
+- [X] Modifier l'intégralité du code pour que l'application utilise désormais le MVVM Community Toolkit à la place du toolkit personnel
+    * lecture de la documentation et implémentation dans la branche `TP3` (à affiner pour respecter parfaitement le Toolkit)  
+  
+**TP 4** :  
+Ajouter les vues et les VM nécessaires pour permettre :  
+- [x] Le scan de code-barres afin d'ajouter de nouveaux livres  
+    * le scan de code-barres fonctionne mais le livre n'est pas encore directement ajouté dans la liste (affichage de l'isbn dans en bas de page & du bouton d'ajout du livre)
+- [X] La recherche en ligne (via le web service)
+    * il est possible d'accéder à la page d'un livre en ligne en cliquant dans la partie "Infos en ligne" de la page Détails
