+## Description
+
+[Nest](https://github.com/nestjs/nest) framework TypeScript archetype repository.
+
+## Installation
+
+```bash
+$ npm install
+```
+
+## Running the app
+
+```bash
+# development
+$ npm run start
+
+# watch mode
+$ npm run start:dev
+
+# production mode
+$ npm run start:prod
+```
+
+## Test
+
+```bash
+# unit tests
+$ npm run test
+
+# e2e tests
+$ npm run test:e2e
+
+# test coverage
+$ npm run test:cov
+```
+
+## Authentication functionality
+
+All done with the `Auth` decorator, which lets you determine a list of authorized roles.
+
+The are 3 available roles:
+
+- Public: no role nor user needed
+- User
+- Admin
+
+These can be extended by simply adding new elements to the `src/users/roles/role.enum.ts` enumeration.
+
+```ts
+@Auth(Role.Public)
+@Get()
+getHello(): string { return "Hello!" }
+```
+
+### JWT
+
+User login is managed by a `JWT` based structure. The client must send both username and password in the body of a `POST` method at `/auth/login`, which would return a `JWT` in case of success. This token must be used to interact with the server on every non-public route. Internally the server assumes the user passwords are stored hashed on a [Mariadb](https://mariadb.org/) database.
