-1. We import the necessary modules from SQLAlchemy: `create_engine`, `declarative_base`, and `sessionmaker`.
-2. We define the SQLite database URL using `SQLALCHEMY_DATABASE_URL = "sqlite:///./blog_app.db"`. This will create a new SQLite database file named `blog_app.db` in the current directory if it doesn't exist, or use the existing one if it does.
-3. We create the SQLAlchemy engine using `create_engine(SQLALCHEMY_DATABASE_URL, connect_args={"check_same_thread": False})`. The `connect_args` parameter is required for SQLite to avoid threading issues.
-5. We create a `Base` class using `declarative_base()`. This class will be used as the base class for defining database models.

-This code defines CRUD (Create, Read, Update, Delete) endpoints for the `User` model using the FastAPI router. Here's a breakdown of the code:
+This file defines the following endpoints:
 
 
-Note that this code assumes the existence of the following components:
+The endpoints use SQLAlchemy models and Pydantic schemas for data validation and serialization. The `get_current_user` dependency is used to ensure that only authenticated users can access certain endpoints (e.g., read all users, read a single user, update a user, and delete a user).
+
+Note that you'll need to define the `User`, `UserCreate`, `UserRead`, and `UserUpdate` models and schemas in separate files (e.g., `app/models.py` and `app/schemas/user.py`). Additionally, you'll need to implement the `get_current_user` function in `app/core/security.py` to handle user authentication and authorization.
