-- [x] Database Connection Using SQLAlchemy
-- [x] FastAPI Server
-- [x] Unit Testing with PyTest
-- [x] Basic CRUD for Posts
+## Requirements
+- Python 3.10+
+- `pip`
+- PostgreSQL database
 
-<br>
+## Setup
+1. Create and activate a virtual environment:
 
-## Dependencies
+```bash
+python3 -m venv .venv
+source .venv/bin/activate
+```
+
+2. Install dependencies:
+
+```bash
+pip install -r requirements.txt
+```
 
-- Python 3.7+
-- Pip
-- Other listed in requirements.txt
+3. Set environment variables:
 
-## Running
+| Key | Value |
+| --- | --- |
+| `DATABASE_URL` | `postgresql://user:password@host:port/db` |
 
-- Clone the repo using
+Example (`.env`):
 
-```bash
-git clone https://github.com/mdhishaamakhtar/fastapi-sqlalchemy-postgres-template
+```env
+DATABASE_URL=postgresql://postgres:postgres@localhost:5432/fastapi_template
 ```
 
-- Create a Virtual Environment using
+4. Run the API:
 
 ```bash
-sudo pip install virtualenv
-virtualenv env
+uvicorn main:app --reload
 ```
 
-- Activate the virtualenv
+## API Docs (Swagger / OpenAPI)
+Once the app is running locally, open:
+- Swagger UI: `http://127.0.0.1:8000/docs`
+- ReDoc: `http://127.0.0.1:8000/redoc`
+- OpenAPI JSON: `http://127.0.0.1:8000/openapi.json`
 
+## Running tests
 ```bash
-env\Scripts\activate # for windows
-source env/bin/activate # for linux and mac
+pytest
 ```
 
-- Install dependencies
+## Formatting (Black)
+Run formatter:
 
 ```bash
-pip install -r requirements.txt
+black .
 ```
 
-- Setting up environment variables
+## Docker (Local)
+1. Create `.env` from example:
 
-| Key     | Value |
-| ----------- | ----------- |
-| DATABASE_URL   | postgresql://user:password@host:port/db|
+```bash
+cp .env.example .env
+```
 
-- To run the project
+2. Start API + Postgres with Docker Compose:
 
 ```bash
-uvicorn main:app
+docker compose up --build
 ```
