+## Generating PDFs for Reports
+
+To generate PDFs for reports, the application uses Laravel Snappy. The Laravel Snappy package is already included in the application, but you need to install Wkhtmltopdf separately.
+
+### Wkhtmltopdf Installation
+
+1. **Download and install Wkhtmltopdf**
+   - [Wkhtmltopdf Downloads](https://wkhtmltopdf.org/downloads.html)
+   
+   - Alternatively, if you are using Homebrew on macOS, you can install it using the following command:
+     ```bash
+     brew install wkhtmltopdf
+     ```
+
+2. **Configure the binary paths**
+   - If needed, you can change the paths to the Wkhtmltopdf binaries in the Snappy configuration file (`config/snappy.php`).
+
+For detailed installation instructions, refer to the [Laravel Snappy documentation](https://github.com/barryvdh/laravel-snappy).
