 ## Usage
 
-todo
+Firstly, you have to create your form inputs.
+
+```dart
+static List<FormInput> getNormalEntries() {
+    return const [
+        FormInput(formFieldName, Name.pure()),
+        FormInput(formFieldEmail, Email.pure()),
+        FormInput(formFieldPhone, Phone.pure()),
+        FormInput(formFieldList, ListOption<String>.pure(defaultValue: ['checkbox3'])),
+        FormInput(formFieldRadio, TextString.pure()),
+        FormInput(formFieldPro, Boolean.pure(), metadata: FormInputMetadata<void>(name: 'business')),
+        FormInput(formFieldHidden, Boolean.pure(), metadata: FormInputMetadata<void>(export: false)),
+    ];
+}
+
+static List<FormInput> getBusinessEntries() {
+    const entries = [
+        FormInput(formFieldSiren, Siren.pure()),
+        FormInput(formFieldIban, Iban.pure()),
+    ];
+    return getNormalEntries() + entries;
+}
+
+static FormData getNormalFormData() {
+    return FormData(getNormalEntries());
+}
+
+static FormData getProFormData() {
+    return FormData(getBusinessEntries());
+}
+```
+
+> Let's create functions to enable dynamic changes in runtime.
+
+> When creating metadata with `FormInputMetadata<T>`, `T` is the type of `extra` object.
+
+Then a `FormData` is a collection of inputs. You can `validate`, `contains`, `intersection`, `difference`, `union`, or `clone` this data.
+
+After that, you have to extends `FormDataCubit`.
+
+```dart
+class CustomFormCubit extends FormDataCubit {
+  CustomFormCubit({required FormData inputs}) : super(inputs: inputs);
+
+  @override
+  Future<void> submitForm() {
+    log(state.data.toMap().toString());
+    // Handle all your logic here.
+    emit(...)
+  }
+}
+```
+
+> The submited form is in `state.data` !
+
+Don't forget to create and provide it !
+
+```dart
+FormDataCubit _formCubit = CustomFormCubit(inputs: getNormalFormData());
+
+return BlocProvider(
+    create: (context) => _formCubit,
+    child: const WidgetTree(),
+);
+```
+
+You can now create the first form input !
+
+```dart
+class _EmailInput extends StatelessWidget {
+  @override
+  Widget build(BuildContext context) {
+    return BlocBuilder<FormDataCubit, FormDataState>(
+      builder: (context, state) {
+        return TextField(
+          onChanged: (email) => context
+              .read<FormDataCubit>()
+              .dataChanged(formFieldEmail, Email.dirty(email)),
+          keyboardType: TextInputType.emailAddress,
+          decoration: InputDecoration(
+            labelText: 'email',
+            helperText: '',
+            errorText: state.data.isNotValid(formFieldEmail)
+                ? 'invalid email'
+                : null,
+          ),
+        );
+      },
+    );
+  }
+}
+```
+
+Then, you can create the trigger
+
+```dart
+class _SignUpButton extends StatelessWidget {
+  @override
+  Widget build(BuildContext context) {
+    return BlocBuilder<FormDataCubit, FormDataState>(
+      buildWhen: (previous, current) => previous.status != current.status,
+      builder: (context, state) {
+        return state.status.isSubmissionInProgress
+            ? const CircularProgressIndicator()
+            : ElevatedButton(
+                onPressed: state.status.isValidated
+                    ? () => context.read<FormDataCubit>().submitForm()
+                    : null,
+                child: const Text('SIGN UP'),
+              );
+      },
+    );
+  }
+}
+```
+
+> With `state.status` you can access the status of the form to check if there is an error or if it's in submission.

+</p>
 
-TODO: List what your package can do. Maybe include images, gifs, or videos.
+HTTP Client for Dart with Middlewares !
 
 ## Getting started
 
-TODO: List prerequisites and provide or point to information on how to
-start using the package.
+Simply add wyatt_http_client in pubspec.yaml, then
+
+```dart
+import 'package:wyatt_http_client/wyatt_http_client.dart';
+```
 
 ## Usage
 
-TODO: Include short and useful examples for package users. Add longer examples
-to `/example` folder. 
+Firstly you have to understand **Middleware** and **Pipeline** concepts.
+
+In `wyatt_http_client` a middleware is an object where requests and responses 
+pass through. And a pipeline is basicaly a list of middlewares.
+
+In a pipeline with middlewares A and B, if request pass through A, then B, 
+the response will pass through B then A.
+
+> You can `print(pipeline)` to get full process order of a pipeline.
+
+For example, if you want to log every request, and simplify an url you can use provided `SimpleLogger` and `UriPrefix` .
 
 ```dart
-const like = 'sample';
+// Create the Pipeline
+final Pipeline pipeline = Pipeline()
+    .addMiddleware(
+        UriPrefixMiddleware(
+            protocol: Protocols.http,
+            authority: 'localhost:80',
+        ),
+    )
+    .addMiddleware(SimpleLoggerMiddleware());
 ```
 
-## Additional information
+Then if you print the pipeline, 
 
-TODO: Tell users more about the package: where to find more information, how to 
-contribute to the package, how to file issues, what response they can expect 
-from the package authors, and more.
+```
+[Req] -> UriPrefix -> SimpleLogger
+[Res] -> SimpleLogger
+```
+
+> The `response` doesn't pass through `UriPrefix` because it's an `OnRequestMiddleware` only.
+
+And you can create a client.
+
+```dart
+final client = MiddlewareClient(pipeline: pipeline);
+```
+
+At this point you can use `client` like every Client from `package:http/http.dart` .
+
+## Recipes
+
+### Rest API with URL Authentication
+
+Let's build a client for a REST API where the (bad) authentication is through the URL.
+We need some middlewares:
+
+* SimpleLogger, to log every request and response (useful for debug).
+* BodyToJson, to automaticaly transform Map object to JSON.
+* UriPrefix, to simplify the build of an API Object (save protocol and API prefix).
+* UnsafeAuth, to use url based authentication.
+
+Let's start by creating the Pipeline:
+
+```dart
+final Pipeline pipeline = Pipeline()
+    .addMiddleware(
+        UriPrefixMiddleware(
+            protocol: Protocols.http,
+            authority: 'localhost:80',
+        ),
+    )
+    .addMiddleware(BodyToJsonMiddleware())
+    .addMiddleware(
+        UnsafeAuthMiddleware(
+            username: 'wyatt',
+            password: 'motdepasse',
+        ),
+    )
+    .addMiddleware(SimpleLoggerMiddleware());
+```
+
+Then simply create a client and make a call.
+
+```dart
+final client = MiddlewareClient(pipeline: pipeline);
+
+await client.get(Uri.parse('/protected'));
+```
+
+> Here it make a `GET` call on `http://localhost:80/protected?username=wyatt&password=motdepasse`
+
+And voilà.
+
+### Rest API with Oauth2
+
+So now we want a real authentication.
+
+```dart
+final Pipeline pipeline = Pipeline()
+    .addMiddleware(
+        UriPrefixMiddleware(
+            protocol: Protocols.http,
+            authority: 'localhost:80',
+        ),
+    )
+    .addMiddleware(BodyToJsonMiddleware())
+    .addMiddleware(
+        RefreshTokenAuthMiddleware(
+            authorizationEndpoint: '/auth/sign-in',
+            tokenEndpoint: '/auth/refresh',
+            accessTokenParser: (body) => body['access_token']! as String,
+            refreshTokenParser: (body) => body['refresh_token']! as String,
+            unauthorized: HttpStatus.forbidden,
+        ),
+    )
+    .addMiddleware(SimpleLoggerMiddleware());
+```
+
+> Here we just change `UnsafeAuthMiddleware` by `RefreshTokenAuthMiddleware` and the whole app while adapt to a new authentication system.
+
+### Create a new Middleware
+
+You can create your own middleware by implementing `Middleware` class, and use mixins to add `OnRequest` and/or `OnResponse` methods.
+
+```dart
+class SimpleLoggerMiddleware 
+    with OnRequestMiddleware, OnResponseMiddleware 
+    implements Middleware {
+  
+  @override
+  String getName() => 'SimpleLogger';
+
+  @override
+  Future<MiddlewareRequest> onRequest(
+    MiddlewareContext context,
+    MiddlewareRequest request,
+  ) async {
+    print('${getName()}::OnRequest');
+    return request;
+  }
+
+  @override
+  Future<MiddlewareResponse> onResponse(
+    MiddlewareContext context,
+    MiddlewareResponse response,
+  ) async {
+    print('${getName()}::OnResponse');
+    return response;
+  }
+}
+```
