+## Features
+
+- **User Authentication:** Secure user login with password hashing.
+- **JWT Authentication:** Provides JWT token generation with expiration for secure API access.
+- **Post Management:** Create, fetch single posts, update posts, delete posts, like posts, and fetch all posts.
+- **Docker Support:** Easily set up and run the project using Docker Compose.
+- **Environment Configuration:** Example environment files (`.env.example` and `.env.postgres.example`) to help you get started quickly.
+
+## Installation
+
+### Prerequisites
+
+- Docker
+- Docker Compose
+
+### Steps
+
+1. Clone the repository:
+
+    ```bash
+    git clone https://github.com/resist15/SocialPulse.git
+    cd SocialPulse
+    ```
+
+2. Copy the example environment variable files and configure them as needed:
+
+    ```bash
+    cp .env.example .env
+    cp .env.postgres.example .env.postgres
+    ```
+
+3. Build and run the containers using Docker Compose:
+
+    ```bash
+    docker-compose up --build
+    ```
+
+    This will start the FastAPI application along with any required services like the database.
+
+4. The application will be running at `http://127.0.0.1:8000`.
+
+## Usage
+
+### Access the API
+
+1. **Interactive API Documentation:**
+
+   - Open your browser and navigate to `http://127.0.0.1:8000/docs` for the Swagger UI.
+   - Or go to `http://127.0.0.1:8000/redoc` for ReDoc.
+
+2. **Test the API Endpoints:**
+
+   You can use the interactive documentation to test the endpoints directly from your browser.
+
+## API Endpoints
+
+- **Authentication:**
+  - `POST /auth/`: Authenticate a user and receive a JWT token.
+- **User Management:**
+  - `POST /users/`: Create a new user.
+  - `GET /users/{id}/`: Fetch the current user's details.
+- **Post Management:**
+  - `POST /posts/`: Create a new post.
+  - `GET /posts/{id}`: Fetch a single post by ID.
+  - `GET /posts/`: Fetch all posts.
+  - `PUT /posts/{id}`: Update post.
+  - `DEL /posts/{id}`: Delete post.
+  - `POST /like/`: Like a post.
+
+### Example Request: User Login
+
+```bash
+curl -X 'POST' \
+  'http://127.0.0.1:8000/auth/' \
+  -H 'Content-Type: application/json' \
+  -d '{
+  "username": "user1",
+  "password": "password123"
+}'
+```
+### Example Response: JWT Token
+
+```
+{
+  "access_token": "your.jwt.token",
+  "token_type": "bearer"
+}
+```
+## Configuration
+
+The application uses environment variables for configuration. Example environment variable files have been provided:
+
+- **`.env.example`**: General environment variables for the application.
+- **`.env.postgres.example`**: Environment variables specific to PostgreSQL configuration.
+
+To use them:
+
+1. Copy the example files to `.env` and `.env.postgres`.
+2. Edit the files to include your specific configuration details, such as database credentials, JWT secret keys, etc.
+
+Docker Compose will automatically load these environment variables.
