- Pretty print an HTML file:

`tidy {{path/to/file.html}}`

- Enable indentation, wrapping lines in 100, saving to `output.html`:

`tidy {{[-i|--indent]}} y {{[-w|--wrap]}} 100 {{[-o|-output]}} {{path/to/output.html}} {{path/to/file.html}}`

- Modify an HTML file in-place using a configuration file:

`tidy -config {{path/to/configuration}} {{[-m|-modify]}} {{path/to/file.html}}`
