## Overview

Chess Master’s backend is a Django REST API for account registration and login, JWT issuance, user/profile access, and recording and listing games. The main request path enters through the project URL configuration, is dispatched to API views, and uses serializers and models to produce responses and persist data. PostgreSQL is configured as the database. The README documents the public API capabilities; sampled source confirms the view, model, and serializer roles, though the API URL mappings and model/serializer details were not sampled.

Main entry points: [`chessapi/api/views.py`](https://github.com/jin2oo2/chess-backend/blob/main/chessapi/api/views.py) (API views), [`chessapi/chessapi/urls.py`](https://github.com/jin2oo2/chess-backend/blob/main/chessapi/chessapi/urls.py) (Project URLs), [`chessapi/api/urls.py`](https://github.com/jin2oo2/chess-backend/blob/main/chessapi/api/urls.py) (API routes), [`chessapi/api/models.py`](https://github.com/jin2oo2/chess-backend/blob/main/chessapi/api/models.py) (User data)
