-# Ruby Hello World Web Server
+# featurevisor-example-ruby
 
-A simple Ruby web server that demonstrates basic HTTP server concepts with a Hello World response.
-
-## Features
-
-- Lightweight HTTP server built with pure Ruby
-- Responds with "Hello World" on the root endpoint
-- Request logging and error handling
-- Graceful shutdown with Ctrl+C
-
-## Prerequisites
-
-- Ruby 2.7.0 or higher
-- Bundler (for managing dependencies)
+Example Ruby web server that demonstrates how to use Featurevisor SDK.
 
 ## Installation
 
-1. **Clone or download this repository**
-   ```bash
-   git clone <repository-url>
-   cd featurevisor-example-ruby
-   ```
-
-2. **Install dependencies**
-   ```bash
-   bundle install
-   ```
-   
-   Or use the rake task:
-   ```bash
-   rake install
-   ```
-
-## Running the Web Server
-
-### Method 1: Using Rake (recommended)
-```bash
-rake run
-```
-
-### Method 2: Direct Ruby execution
-```bash
-ruby app.rb
-```
-
-### Method 3: Start in background
-```bash
-rake start
-```
-
-### Method 4: Make the file executable and run
-```bash
-chmod +x app.rb
-./app.rb
-```
-
-## Accessing the Server
-
-Once the server is running, you can access it at:
-
-- **Main endpoint**: http://localhost:3000
-
-## API Endpoints
-
-### GET /
-Returns a simple "Hello World" text response.
-
-**Response:**
-```
-HTTP/1.1 200 OK
-Content-Type: text/plain
-Content-Length: 11
-
-Hello World
-```
-
-## Stopping the Server
-
-- **If running in foreground**: Press `Ctrl+C`
-- **If running in background**: Use `rake stop`
-
-## Available Rake Tasks
-
-- `rake run` - Start the web server in foreground
-- `rake start` - Start the web server in background
-- `rake stop` - Stop the background web server
-- `rake check_port` - Check if port 3000 is available
-- `rake install` - Install gem dependencies
-- `rake lint` - Run RuboCop for code style checking
-- `rake clean` - Clean temporary files
-

-## Development
-
-### Code Style
-This project uses RuboCop for code style enforcement. Run it with:
-```bash
-bundle exec rubocop
-```
+## Usage
 
-### Port Configuration
-The server runs on port 3000 by default. You can change this by modifying the port number in `app.rb` or by creating a new instance with a different port.
+Run the server locally, running:
 
-## Troubleshooting
-
-### Port already in use
-If you get an "Address already in use" error, check if port 3000 is available:
-```bash
-rake check_port
 ```
-
-### Ruby not found
-If you get a "ruby: command not found" error, make sure Ruby is installed and in your PATH.
-
-### Bundler not found
-Install Bundler with:
-```bash
-gem install bundler
-```
-
-### Permission denied
-If you get a permission error when running `./app.rb`, make sure the file is executable:
-```bash
-chmod +x app.rb
-```
-
-## Example Usage
-
-### Starting the server:
-```bash
 $ rake run
-Starting Ruby Hello World Web Server...
-Starting Hello World Web Server on port 3000...
-Visit http://localhost:3000 in your browser
-Press Ctrl+C to stop the server
-
-2024-01-15 10:30:00 - GET /
-2024-01-15 10:30:05 - GET /
 ```
 
-### Testing with curl:
-```bash
-# Test main endpoint
-curl http://localhost:3000/
-# Output: Hello World
-```
