+//! # Authentication flow
+//! Before being able to authenticate, the user needs to create an account
+//! Here's how it can be done:
+//! - The user submits information on the client
+//! - The client sends a request to the "register" endpoint
+//! - The endpoint ensures the information given is valid
+//! - An account is created
+//! - The user is redirected to the login page
+//!
+//! After, the user can authenticate
+//! Here's how it works:
+//! - The users submits information on the client
+//! - The client sends a request to the "login" endpoint
+//! - The endpoint makes sure the information given is valid (otherwise reject the request: no db call)
+//! - Then it checks that the user exists
+//! - Then it checks that the correct password was given
+//! - Then it creates two tokens: a short-lived and a refresh-token
+//! - The short-lived token must be saved in local-storage and the refresh-token must be saved as a http only cookie
+//!
+//! Once authenticated, the short-lived token can be renewed
+//! Here's how it works:
+//! - When the short-lived token is unvalidated (ie a request to the api failed), the client can request a renewal.
+//! - The renewal request contains the now unvalid token with the refresh-token cookie.
+//! - The server checks that the refresh-token is valid (good user, not expired, ...)
+//! - If checks pass, the server generates a new short-lived token.
+//! - If it fails, the client redirects the user to login.
