+# Go Book API Example
+
+This is a simple Go web service that provides a basic API for retrieving book information. It's built using the `chi` router and serves hardcoded book data from memory.
+
+## Project Structure
+
+- `main.go`: Application entry point, sets up the HTTP server and defines the `/books/{id}` endpoint.
+- `internal/handlers/book_handler.go`: Contains the `BookHandler` responsible for processing requests to the `/books/{id}` endpoint. It uses an in-memory list of books.
+- `internal/models/book.go`: Defines the `Book` struct used to represent book data.
+
+## Getting Started
+
+### Prerequisites
+
+- Go (version 1.16 or higher recommended)
+
+### Running the Application
+
+1. **Clone the repository:**
+   ```bash
+   git clone <repository_url>
+   cd testing-go-example
+   ```
+   (Note: Replace `<repository_url>` with the actual repository URL if this project were hosted.)
+
+2. **Run the server:**
+   ```bash
+   go run main.go
+   ```
+   The server will start on `http://localhost:3000`.
