-# playground-rs
+# Playground RS
 
+A simple multi-threaded web server implementation in Rust. This project demonstrates the implementation of a basic HTTP server with a thread pool for handling concurrent connections.
+
+## Features
+
+- Multi-threaded web server implementation
+- Custom thread pool for handling concurrent connections
+- Basic HTTP response handling
+- Graceful shutdown mechanism
+
+## Project Structure
+
+- `src/main.rs` - Entry point of the application
+- `src/server.rs` - Web server implementation
+- `src/thread_pool.rs` - Custom thread pool implementation
+
+## Requirements
+
+- Rust 2024 edition
+- Cargo (Rust's package manager)
+
+## Running the Project
+
+1. Clone the repository:
+```bash
+git clone <repository-url>
+cd playground-rs
+```
+
+2. Build and run the project:
+```bash
+cargo run
+```
+
+The server will start on `127.0.0.1:7878`. You can test it by opening a web browser and navigating to `http://127.0.0.1:7878` or using curl:
+
+```bash
+curl http://127.0.0.1:7878
+```
+
+## Implementation Details
+
+### Thread Pool
+
+The project implements a custom thread pool that:
+- Creates a fixed number of worker threads
+- Uses message passing for job distribution
+- Handles graceful shutdown
+- Manages thread lifecycle
+
+### Web Server
+
+The web server:
+- Listens on localhost port 7878
+- Uses the thread pool to handle incoming connections
+- Responds with a simple "Hello, world!" message
