-├── App.js          # Main component with JMESPath logic
-├── App.css         # App-specific styles
-├── App.test.js     # Basic tests

-## Key Features Implemented
-
-1. **Real-time JMESPath Evaluation**: Uses the `jmespath` library to evaluate expressions as user types
-2. **JSON Validation**: Parses and validates JSON input with error reporting
-3. **Bootstrap UI**: Responsive layout with cards, buttons, and form controls
-4. **Error Handling**: Clear error messages for both JSON and JMESPath syntax issues
-5. **Sample Data**: Pre-loaded examples with "Load Sample" button
-6. **JSON Formatting**: "Format JSON" button to prettify JSON input
-7. **Clear Function**: "Clear All" button to reset all inputs
-
-## Component Architecture
-
-The main `App.js` component manages:
-- State for JMESPath expression, JSON data, results, and errors
-- Auto-evaluation using `useEffect` when inputs change
-- Error handling for both JSON parsing and JMESPath evaluation
-- UI event handlers for buttons and input changes
-
-## Styling
-
-- Bootstrap 5.3.2 for responsive grid and components
-- Custom CSS for enhanced UX (color coding, hover effects)
-- Gradient header with professional appearance
-- Color-coded input areas (yellow for JMESPath, green for JSON, blue for results)
-
-## Browser Compatibility
-
-Built with React 18 and targets:
-- Modern evergreen browsers
-- Node.js 24 LTS compatibility
-- Mobile-responsive design

-The application is divided into three main sections:
-
-1. **Top Section**: Title and description of the tool
-2. **Middle Section**: Input area for JMESPath expressions
-3. **Bottom Sections**: 
-   - **Left**: JSON data input area
-   - **Right**: Query results output area
 
 ## Quick Start
 
 ### Prerequisites
 
 - Node.js 24 LTS or higher
-- npm or yarn package manager
+- npm package manager
 
 ### Local Development
 
 1. **Clone the repository**:
+
    ```bash
    git clone <repository-url>
    cd jmespath-playground
    ```
 
 2. **Install dependencies**:
+
    ```bash
    npm install
    ```
 
 3. **Start the development server**:
+
    ```bash

 ## Usage
@@ -82,93 +73,56 @@ docker run -p 3000:3000 jmespath-playground
    - Format JSON for better readability
    - Clear all inputs
 
-### Example JMESPath Expressions
+## Remote API Usage
 
-Try these examples with the sample data:
+The application includes a REST API for uploading sample data remotely:
 
-- `people[*].name` - Get all names
+1. **Access API Key**: Click the key-lock button (🔒) to view your unique API key
-- `people[0]` - Get the first person
+2. **Upload Data**: Use curl or any HTTP client to upload JSON data:
-- `people[?age > 30]` - Filter people older than 30
+   ```bash
-- `people[*].skills[0]` - Get the first skill of each person
+   curl -X POST \
-- `length(people)` - Count the number of people
+       -H "Content-Type: application/json" \
+       -H "X-API-Key: YOUR_API_KEY" \
+       --data @sample-data.json \
+       "http://your-domain.com/api/v1/upload"
+   ```
+3. **Auto-reload**: The running app will detect new data and show a reload button
 
-## Available Scripts
+**API Endpoints:**
+- `POST /api/v1/upload` - Upload sample data
+- `GET /api/v1/sample` - Retrieve current sample data
+- `GET /api/v1/state` - Get current state ID
+- `GET /api/v1/health` - Simple health check (returns "OK")
+- `GET /api/v1/status` - Detailed status information (JSON)
 
-In the project directory, you can run:
+## Server Configuration
 
-### `npm start`
+The server can be configured using environment variables:
 
-Runs the app in development mode. The page will reload when you make edits.
+**Network Settings:**
+- `LISTEN_ADDR` - Server bind address (default: `127.0.0.1`)
+- `LISTEN_PORT` - Server port (default: `3000`)
 
-### `npm test`
+**Session Management:**
+- `MAX_SESSIONS` - Maximum number of concurrent sessions (default: `100`)
+- `MAX_SAMPLE_SIZE` - Maximum size of uploaded sample data in bytes (default: `1048576` - 1MB)
+- `MAX_SESSION_TTL` - Session time-to-live in milliseconds (default: `3600000` - 1 hour)
 
-Launches the test runner in interactive watch mode.
+Example usage:
 
-### `npm run build`
+```bash
-
+MAX_SESSIONS=200 MAX_SAMPLE_SIZE=2097152 LISTEN_PORT=8080 node server.js
-Builds the app for production to the `build` folder. It correctly bundles React in production mode and optimizes the build for the best performance.
-
-### `npm run serve`
-
-Serves the production build locally on port 3000.
-
-### Docker Scripts
-
-### `npm run docker:build`
-
-Builds a Docker container.
-
-### `npm run docker:run`
-
-Runs the Docker container.
