+# Sysdig Inspect React Frontend
+
+This document explains how to use the new React.js frontend for Sysdig Inspect.
+
+## Overview
+
+The original Sysdig Inspect frontend was built with Ember.js. This project includes a new frontend implementation using React.js and Redux, which maintains the same visual appearance and functionality as the original.
+
+The backend and controller remain unchanged, allowing you to switch between the Ember.js and React.js frontends as needed.
+
+## Getting Started
+
+### Prerequisites
+
+- Node.js 16 or higher
+- npm 7 or higher
+
+### Setup
+
+1. First, set up the React frontend:
+
+```bash
+npm run setup:react
+```
+
+This will install all the necessary dependencies for the React frontend.
+
+### Running the Application
+
+You can run the React frontend in two ways:
+
+#### Option 1: Run the complete application (backend + React frontend)
+
+```bash
+# On Linux/macOS
+npm run start:react-app
+
+# On Windows
+npm run start:win:react-app
+```
+
+This will start both the backend server and the React frontend. The React frontend will be available at http://localhost:3001 and will communicate with the backend at http://localhost:3000.
+
+#### Option 2: Run the backend and frontend separately
+
+```bash
+# Start the backend
+npm run start:backend  # or npm run start:win:backend on Windows
+
+# In a separate terminal, start the React frontend
+npm run start:react
+```
+
+### Building for Production
+
+To build the React frontend for production:
+
+```bash
+npm run build:react
+```
+
+This creates a production build in the `react-frontend/build` directory.
+
+### Docker
+
+You can also build and run the React frontend in a Docker container:
+
+```bash
+npm run make:react-docker-image
+docker run -p 80:80 --name sysdig-inspect-react sysdig-inspect-react
+```
+
+## Switching Between Frontends
+
+You can easily switch between the original Ember.js frontend and the new React.js frontend:
+
+- To use the Ember.js frontend: `npm run start:webapp`
+- To use the React.js frontend: `npm run start:react`
+
+Both frontends communicate with the same backend server.
+
+## Project Structure
+
+The React frontend is located in the `react-frontend` directory and has the following structure:
+
+- `src/components`: Reusable UI components
+- `src/pages`: Page components that correspond to routes
+- `src/store`: Redux store configuration and slices
+- `src/services`: API and utility services
+- `src/styles`: LESS stylesheets
+- `public`: Static assets
