 ### Running Backend & Frontend Separately (Docker + Kubernetes)
+
+### Prerequisites
+
+Before you begin, make sure you have:
+
+- A Kubernetes cluster up and running.
+- `kubectl` installed and configured to communicate with your cluster.
+- Proper permissions to create Deployments, Services, Persistent Volumes, and other Kubernetes resources.
+
+### Overview of Components
+
+- `frontend_deployment.yaml`: Deployment for the SafeShare frontend.
+- `frontend_service.yaml`: Service exposing the SafeShare frontend.
+- `backend_deployment.yaml`: Deployment for the SafeShare backend.
+- `backend_service.yaml`: Service exposing the SafeShare backend.
+- `redis_deployment.yaml`: Setup for Redis with persistent storage.

 ```bash
 # Run frontend using docker-compose
 docker compose -f  docker-compose-frontend.yml up -d

+## Test Files
+
+Theoretically, the application can handle any type of file. However, we have tested the application with the following file types:
+- Text-based `.txt`, `.py`, etc.
+- Image-based `.png`, `.jpg`, etc.
+- Video-based `.mp4`, etc.
+- Executable `.exe`, etc.
