+## 📘 API Documentation
+
+Interactive API documentation is available out of the box thanks to Swagger UI and the generated OpenAPI specification.
+
+1. Run the application locally:
+
+```bash
+./mvnw spring-boot:run
+```
+
+2. Open [http://localhost:8080/swagger-ui/index.html](http://localhost:8080/swagger-ui/index.html) in your browser to explore and try the endpoints.
+
+The raw OpenAPI document can be downloaded from [http://localhost:8080/v3/api-docs](http://localhost:8080/v3/api-docs) for integration with other tools.
+
+---
+## 🚀 Getting Started
+
+### 1. Prerequisites
+
+- Java 17+
+- Maven
+- Email SMTP (Gmail or others)
+- Firebase Project (Firestore + Service Account)
+
+### 2. Clone the repo
+
+```bash
+git clone https://github.com/HacktoberBlog/SpringBootBackend.git
+cd SpringBootBackend
+```
+
+### 3. Firebase Setup
+
+- Go to Firebase Console
+
+- Create a project
+
+- Enable Firestore
+
+- Generate a Service Account Key JSON file
+
+- Save the file in a secure path, e.g., /etc/secrets/firebaseServiceAccountKey.json
+
+### 4. Configure Email 
+
+Edit src/main/resources/application.properties:
+
+```
+spring.mail.host=smtp.gmail.com
+spring.mail.port=587
+spring.mail.username=your_email@gmail.com
+spring.mail.password= 16 char app key such as abcd efgh ijkl mnop
+spring.mail.properties.mail.smtp.auth=true
+spring.mail.properties.mail.smtp.starttls.enable=true
+redis.password= your redis db password
+```
+
+#### Getting Keys/Passwords for Email, DB, etc.
+Gmail 16 char App Key: You can get the app key by navigating to google myaccount settings->search app passwords->give an app name-> create and copy the key
+
+Redis Password: You can create a free db on [Redis](https://redis.io/). Once your db is created, click on the "Connect using Redis CLI, Client, or Insight" button. There you will be able to view your password (view/hide it using eye icon)
+
+
+### 🔑 Setup Secrets (Environment Variables)
+
+To run the project, you must provide your secrets as environment variables.  
+These are used in `application.properties` via Spring's placeholder system:
+
+| Variable Name                   | Description                                   | Example Value                  |
+|---------------------------------|-----------------------------------------------|--------------------------------|
+| `spring.mail.username`          | Your email for sending welcome emails.        | `your_email@gmail.com`         |
+| `spring.mail.password`          | Your 16-char app key for the email account.   | `abcd efgh ijkl mnop`          |
+| `redis.password`                | The password for your Redis database.         | `yourRedisDbPassword123`       |
+
+
+## ⚠️ **NOTE:**  
+**🚫 DO NOT PUSH** the changes made in `application.properties`, `RedisConfig`, and `FirestoreService`.  
+🔒 _Keep your secrets safe!_ 🔒
