✨(project) first proof of concept based of Joanie

Used https://github.com/openfun/joanie as boilerplate, ran a few
transformations with ChapGPT  and adapted models and endpoints to
fit to my current vision of the project.

+# Api client TypeScript
+
+The backend application can automatically create a TypeScript client to be used in frontend
+applications. It is used in the People front application itself.
+
+This client is made with [openapi-typescript-codegen](https://github.com/ferdikoomen/openapi-typescript-codegen)
+and People's backend OpenAPI schema (available [here](http://localhost:8071/v1.0/swagger/) if you have the backend running).
+
+## Requirements
+
+We'll need the online OpenAPI schema generated by swagger. Therefore you will first need to
+install the backend application.
+
+## Install openApiClientJs
+
+```sh
+$ cd src/tsclient
+$ yarn install
+```
+
+## Generate the client
+
+```sh
+yarn generate:api:client:local <output_path_for_generated_client>
+```
