+
+## Back-end
+
+Conventional but efficient:
+
+- [FastAPI](https://fastapi.tiangolo.com/): _FastAPI is a modern, fast (high-performance), web framework for building
+   APIs with Python 3.8+ based on standard Python type hints._
+- [Pydantic 2](https://docs.pydantic.dev/latest/): _Pydantic is the most widely used data validation library for
+   Python._
+- [Sqlalchemy 2](https://www.sqlalchemy.org/): _SQLAlchemy is the Python SQL toolkit and Object Relational Mapper that
+   gives application developers the full power and flexibility of SQL._
+
+The [Msgspec](https://github.com/jcrist/msgspec) library is used to serialize JSON objects collected from IDFM API
+endpoints, this library being faster than Pydantic.
+
+## Front-end
+
+The component is developed using the [SolidJS](https://www.solidjs.com/) library. It brings the following interesting specificities:
+
+- Share with React the same programmatic structures and support for component.
+- Fine-grained reactivity architecture: no virtual DOM used to update the components, the browser DOM is directly
+  updated by SolidJS.
+
+The front-end tries to be as close as possible to the design defined by the IDFM for the displays deployed by the
+transport operators in Ile-de-France. These specifications are public and available here:
+[PRIM-IDFM](https://prim.iledefrance-mobilites.fr/en/chartes-et-prescriptions).
+
+
+# TODO
+
+## Features
+
+- [ ] Integration with [Matrix.org](https://matrix.org/ecosystem/integrations/) ecosystem: make the app able to send message to a room when a bus/train/metro will
+      arriving in X minutes.
+- [ ] Add the capability for the users to pin his/her favorite stops.
+- [ ] Add the address to the stop location.
+
+## Docs
+
+- [ ] Describe how to build the front-end and back-end docker images.
+- [ ] Describe how to deploy them using `docker compose`.
+- [ ] Add back-end API description ([openAPI](https://www.openapis.org/)) + generate documentation
+      ([mkdoc](https://www.mkdocs.org/), [Redoc](https://github.com/Redocly/redoc)). The best would be to build and
+      deploy it (as docker images) using CI/CD... need to test [Agola](https://agola.io/), [Jaypore
+      CI](https://www.jayporeci.in/) (pipelines configured in Python),
+      [Woodpecker](https://woodpecker-ci.org/docs/intro) or [Drone](https://www.drone.io/) before.
+
+## Front-end
+
+- [ ] Add unit tests.
+- [ ] Make the StopNameInput component liquid.
+- [ ] Liquid to responsive Design.
+
+## Back-end
+
+- [ ] Add unit tests.
+- [ ] Use [alembic](https://alembic.sqlalchemy.org/en/latest/) to manage the future updates of the database schemas.
+- [ ] Add the capability to reload the application configuration on configuration file update (e.g.: credential update by the vault).
+- [ ] Rework how the database is updated with the IDFM data: For now the database is cleaned before refilling. It could
+      be useful to avoid to empty the database and only apply deltas (update/add/remove rows).
+- [ ] Could be nice to compare FastAPI with [Litestar](https://litestar.dev/).
