+- [Lcov](https://github.com/linux-test-project/lcov). Used to generate coverage data.
+
+```shell
+# on macos

+```
+
+- genhtml. Used to convert coverage data into html pages.
+
+After installing all these packages, bootstrap with `melos bs`.
 
 ### Create a new package
 
 Create a new package in `packages/` folder.
 
 ```shell
-dart create -t package-simple wyatt_<name>
+mason make wyatt_package --package_name  wyatt_<name> --description A new Wyatt package --flutter_only false
-```
-
-Remove any `example/` subfolder. Then create a new sample project.

-```shell
-flutter create --platforms android --project-name <name>_example example

+### Branches
+
+Master is protected. You can't push on it. Please develop your feature on another branch. The name of your branch has to match with the issue opened.

+When you have finished developing, and are ready to close the issue, close it via your commit :
+
+`feat(auth): add AWS support. (close #31)`
+
+Note that your issue will be close after merging on master.
+Before closing the issue, please check tests and update coverage. You might run :
+
+```shell
+melos run test:all # this will run all tests in this project
+melos run gen-coverage # this will generate coverage report
+melos run gen-class-models # this will generate plantuml class diagrams
+melos run quality-check # this will run all targets generally expected in CI
+melos run publish:validate # this will run a validation before publish packages
+melos run publish # this will publish packages
+```
+
+> Note that only modified package will be verified and published.
+
+#### Merge your work
+
+After closing your issue, some work may have been done on master in the meantime. To keep a clean git history, please rebase before opening a change request.
+
+Two situations :
+
+- You have not yet created your branch and have committed locally :
+
+```shell
+git pull --rebase
+```
+
+- You are already working on your branch :
+
+```shell
+git rebase -i master
+```
+
+If possible, please use `--fixup` on your commit in interactive rebase.
+
+Then, opend your PR, get the necessary approval and merge your work. Then you're done ✅.
+
+#### Update version.
+
+Once your work is on the master, you can update your package version. Please filter packages to update only your package. `--scope` is used to do it.
+For example, after merging changes on `wyatt_otification_bloc` package, you might run :
+
+```shell
+melos version --scope="*wyatt_notification_bloc*"
+```
+
+In fact, melos will filter all packages that match the `wyatt_notification_block` pattern.
+
+You can update check all packages tests by running :
+
+```shell
+melos run test
+```
+
+#### Publish your package
+
+If package is ready for procution, publish it runnig :
+
+```shell
+melos publish --scope"*package*"

+- Classic usecase :

+You can add alternatve scenarios and check pre/post conditions using our extensions :
+
+```dart
+class SearchPhotos extends AsyncUseCase<QueryParameters, List<Photo>>> {
+
+  @override
+  FutureOrResult<List<Photo>>> call(QueryParameters? params) {
+     final photos = _photoRepository.getAllPhotos(
+      start: params.start,
+      limit: params.limit,
+    );
+    return photos;
+  }
+
+
+  @override
+  FutureOr<void> onStart(QueryParameters? params) {
+    if(params.start == null || params.limit == null){
+      throw ClientException('Préconndition non valides');
+    }
+  }
+
+}
+```
+
+You can implement error scenarios overriding `onError`, or check postconditions by overriding `onComplete` .
+
+- Stream usecase :
+
+```dart
+class SearchPhotos extends StreamUseCase<QueryParameters, List<Photo>>> {
+
+  @override
+  FutureOrResult<Stream<List<Photo>>>> call(QueryParameters? params) {
+     final photos = _photoRepository.getAllPhotos(
+      start: params.start,
+      limit: params.limit,
+    );
+    return photos;
+  }
+
+}
+```
+
+On this case, observers allow you to add alternative scénarios when data changed, overriding `onData` or `onDone`.
+
+Please note that to use handlers, call `call` method and not `execute`.
