+## 🚀 Getting Started
+
+### 1️⃣ Clone the Repository
+```bash
+git clone https://github.com/<your-org>/rbac-auth.git
+cd rbac-auth
+```
+### 2️⃣ Install Dependencies
+```
+npm install

+```
+npm run dev
+```
+---
+
+### 🔄 System Flows
+🔑 Authentication Flow
+
+User signs up → password hashed → stored in DB
+
+User logs in → JWT issued
+
+JWT validated for protected routes
+
+RBAC middleware checks user role/permission
+
+### 🛂 Role & Permission Flow
+
+Admin can create roles and assign permissions
+
+Users get assigned roles
+
+Middleware checks role/permission before accessing API
