+# Make your Own Web Application with Hailo and Using Flask 
+
+This tutorial walks you through setting up a Hailo-based web application using Flask. It covers installing necessary dependencies, setting up the environment, and running the server. Here’s a step-by-step breakdown:
+
+### Step 1: Update the System
+
+Open a terminal on your reComputer AI Box and run the following commands to update your system:
+
+```
+sudo apt update
+sudo apt full-upgrade
+```
+### Step 2: Set PCIe to Gen3
+
+Follow the [tutorial](https://seeed-projects.github.io/Tutorial-of-AI-Kit-with-Raspberry-Pi-From-Zero-to-Hero/docs/Chapter_2-Configuring_the_RaspberryPi_Environment/Introduction_to_Hailo_in_Raspberry_Pi_Environment#installing-hailo-software-on-raspberry-pi-5) to set PCIe to Gen3 as required for the Hailo device.
+
+### Step 3: Install Dependencies for NPU
+
+```
+sudo apt install hailo-all
+```
+
+### Step 4: Set Up the Project Environment
+
+- **Create a New Directory**
+
+```
+mkdir Hailo-Web-App
+cd Hailo-Web-App
+```
+- **Create and Activate a Virtual Environment**
+
+```
+python -m venv --system-site-packages env
+source env/bin/activate
+
+```
+- **Clone the Repository**
+
+```
+git clone https://github.com/KasunThushara/Hailo-Web.git
+cd Hailo-Web
+```
+
+- **Install Python Dependencies**
+
+```
+pip install -r requirements.txt
+```
+- **Grant Execution Permission to the Download Script**
+
+```
+chmod +x download_resources.sh
+```
+
+- **Run the Resource Download Script**
+
+```
+./download_resources.sh
+```
+
+### Step 5: Start the Server
+
+- **Navigate Back to the Project Directory at New Terminal**
+
+```
+cd ../Hailo-Web-App
+```
+
+- **Activate the Virtual Environment (if not already activated)**
+
+```
+source env/bin/activate
+```
+
+- **Navigate to the Hailo-Web Directory**
+
+```
+cd Hailo-Web
+```
+
+- **Start the Server**
+
+```
+python3 server.py
+
+```
+
+### Step 6: Access the Web UI
+
+Once the server is running, open a web browser and visit:
+
+```
+http://<pi-ip-address>:5000 
+```
+
+### What You Will Do on the Web UI:
+- Choose the vision task (e.g., object detection, pose estimation).
+- Upload the relevant files for the selected task.
+- View the results directly on the web interface.
+This setup provides a user-friendly interface for interacting with the Hailo device for various vision tasks.
