-    - Account : AccountModel -> Contains account information from provider
+    - Account -> Contains account information from provider.
-    - AccountWrapper : AccountWrapperModel -> Contains account and extra data.
+    - Session -> Contains account and associated data retrieved from an external source.
-- Data Sources:
+    - AuthenticationChangeEvent -> Describes an event in authentication change (sign in, sign up, sign out, etc...)
-    - Local:
+    - SessionWrapper -> Contains latest authentication change event and session.
-        - Cached Authentication Data : AuthenticationCacheDataSourceImpl -> Provides a cache implementation
+* 🔑 Powerful and secured authentication repository
-    - Remote:
+* 🔥 Multiple data sources
-        - Remote Authentication Data : AuthenticationFirebaseDataSourceImpl -> Provides a proxy to FirebaseAuth
+    - Mock
-- Repositories:
+    - Firebase
-    - AuthenticationRepository : AuthenticationRepositoryImpl -> Provides all authentication methods
+* 🧊 Cubits, why make it complicated when you can make it simple?
-- Features:
+    - Goes to the essential.
-    - Authentication:
+* 📐 Consistent
-        - AuthenticationBuilder : widget to build reactive view from authentication state
+    - Every class have same naming convention
-        - AuthenticationCubit : tracks every auth changes, have sign out capability.
+* 🧪 Tested
-    - SignUp:

 ## Getting started
 
-Simply add `wyatt_authentication_bloc` in `pubspec.yaml`, then
+Simply add `wyatt_authentication_bloc` in `pubspec.yaml` , then
 
 ```dart
 import 'package:wyatt_authentication_bloc/wyatt_authentication_bloc.dart';
 ```
 
-## Usage
+### Data source
 
-// TODO
+The first step is to provide a data source.
+
+```dart
+getIt.registerLazySingleton<AuthenticationRemoteDataSource<int>>(
+    () => AuthenticationFirebaseDataSourceImpl<int>(
+        firebaseAuth: FirebaseAuth.instance,
+        googleSignIn:
+            GoogleSignIn(clientId: DefaultFirebaseOptions.ios.iosClientId)),
+);
+```
+
+> Here we use GetIt (see example project)
+
+### Repository
+
+Then you can configure your repository.
+
+```dart
+final AuthenticationRepository<int> authenticationRepository = AuthenticationRepositoryImpl(
+    authenticationRemoteDataSource:
+        getIt<AuthenticationRemoteDataSource<int>>(),
+    customPasswordValidator: const CustomPassword.pure(),
+    extraSignUpInputs: [
+        FormInput(
+        AuthFormField.confirmPassword,
+        const ConfirmedPassword.pure(),
+        metadata: const FormInputMetadata<void>(export: false),
+        ),
+    ],
+);
+```
+
+> Here we pass some extra inputs for the sign up, and a custom password validator.
+
+### Cubits
+
+It is necessary to implement each cubit. Don't panic, most of the work is already done 😊 you just have to customize the logic of these.
+
+In each of these cubits it is necessary to overload the various callbacks.
+
+> Here the associated data `Data` is a `int`
+
+#### Authentication
+
+In the authentication are managed, the refresh, the deletion of account or the disconnection.
+
+```dart
+class ExampleAuthenticationCubit extends AuthenticationCubit<int> {
+  ExampleAuthenticationCubit({required super.authenticationRepository});
+
+  @override
+  FutureOrResult<int?> onReauthenticate(Result<Account, AppException> result) async {
+    // TODO
+  }
+
+  @override
+  FutureOrResult<int?> onRefresh(Result<Account, AppException> result) {
+    // TODO
+  }
+
+  @override
+  FutureOrResult<int?> onSignInFromCache(SessionWrapper<int> wrapper) {
+    // TODO
+  }
+
+  @override
+  FutureOrResult<void> onSignOut() {
+    // TODO
+  }
+
+  @override
+  FutureOrResult<void> onDelete() {
+    // TODO
+  }
+}
+```
+
+#### Sign Up
+
+```dart
+class ExampleSignUpCubit extends SignUpCubit<int> {
+  ExampleSignUpCubit({
+    required super.authenticationRepository,
+  });
+
+  @override
+  FutureOrResult<int?> onSignUpWithEmailAndPassword(Result<Account, AppException> result, WyattForm form) async {
+    // TODO
+  }
+}
+
+```
+
+#### Sign In
+
+```dart
+class ExampleSignInCubit extends SignInCubit<int> {
+  ExampleSignInCubit({
+    required super.authenticationRepository,
+  });
+
+  @override
+  FutureOrResult<int?> onSignInWithEmailAndPassword(Result<Account, AppException> result, WyattForm form) {
+    // TODO
+  }
+
+  @override
+  FutureOrResult<int?> onSignInAnonymously(Result<Account, AppException> result, WyattForm form) {
+    // TODO
+  }
+
+  @override
+  FutureOrResult<int?> onSignInWithGoogle(Result<Account, AppException> result, WyattForm form) {
+    // TODO
+  }
+}
+```
+
+After setting up all these cubits you can provide them in the application. And that's it!
+
+```dart
+BlocProvider<SignUpCubit<int>>(
+    create: (_) => ExampleSignUpCubit(
+        authenticationRepository: authenticationRepository,
+    ),
+),
+BlocProvider<SignInCubit<int>>(
+    create: (_) => ExampleSignInCubit(
+        authenticationRepository: authenticationRepository,
+    ),
+),
+```
+
+### Widgets
+
+Widgets are provided to make your life easier. Starting with the `AuthenticationBuilder` which allows you to build according to the authentication state.
+
+```dart
+AuthenticationBuilder<int>(
+    authenticated: (context, sessionWrapper) => Text(
+        'Logged as ${sessionWrapper.session?.account.email} | GeneratedId is ${sessionWrapper.session?.data}'),
+    unauthenticated: (context) =>
+        const Text('Not logged (unauthenticated)'),
+    unknown: (context) => const Text('Not logged (unknown)'),
+),
+```
+
+A `BuildContext` extension is also available to access certain attributes more quickly.
+
+```dart
+Text('Home | ${context.account<AuthenticationCubit<int>, int>()?.email}'),
+```
+
+Listeners are used to listen to the status of the sign in and sign up forms.
+
+```dart
+return SignInListener<int>(
+    onError: (context, status, errorMessage) => ScaffoldMessenger.of(context)
+    ..hideCurrentSnackBar()
+    ..showSnackBar(
+        SnackBar(content: Text(errorMessage ?? 'Sign In Failure')),
+    ),
+    child: ...
+);
+```
