+
+## Installation
+

 ```
 
-### Rust
+### From source
+
+```bash

+cd epub2mdbook
+cargo install --path .
+```
+
+## Usage
+
+### Command Line
+
+```bash
+# Basic usage - creates a subdirectory named after the book
+epub2mdbook book.epub
+
+# Specify output directory
+epub2mdbook book.epub --output-dir ./output
+
+# Output directly to the directory without creating a subdirectory
+epub2mdbook book.epub --output-dir ./my-book --flat
+```
+

+Add to your `Cargo.toml`:
+
+```toml
+[dependencies]
+epub2mdbook = "0.16"
+```
+
+Then use in your code:
 
 ```rust
 use epub2mdbook::convert_epub_to_mdbook;
 
-convert_epub_to_mdbook("path/to/input.epub", "path/to/output", true);
+fn main() -> Result<(), epub2mdbook::error::Error> {
+    // Creates ./output/book_name/ with the converted content
+    convert_epub_to_mdbook("book.epub", "./output", true)?;
+
+    // Or output directly to ./my-book/ without subdirectory
+    convert_epub_to_mdbook("book.epub", "./my-book", false)?;
+
+    Ok(())
+}
 ```
