 Options:
-- `--output_dir PATH`: Directory where output files will be saved. Defaults to the value specified in settings.OUTPUT_DIR.
+- `--page_range TEXT`: Specify which pages to process. Accepts comma-separated page numbers and ranges. Example: `--page_range "0,5-10,20"` will process pages 0, 5 through 10, and page 20.
 - `--output_format [markdown|json|html]`: Specify the format for the output results.
+- `--output_dir PATH`: Directory where output files will be saved. Defaults to the value specified in settings.OUTPUT_DIR.
 - `--paginate_output`: Paginates the output, using `\n\n{PAGE_NUMBER}` followed by `-` * 48, then `\n\n` 
-- `--use_llm`: Uses an LLM to improve accuracy.  You must set your Gemini API key using the `GOOGLE_API_KEY` env var.
-- `--redo_inline_math`: If you want the highest quality inline math conversion, use this along with `--use_llm`.
-- `--disable_image_extraction`: Don't extract images from the PDF.  If you also specify `--use_llm`, then images will be replaced with a description.
-- `--page_range TEXT`: Specify which pages to process. Accepts comma-separated page numbers and ranges. Example: `--page_range "0,5-10,20"` will process pages 0, 5 through 10, and page 20.
+- `--use_llm`: Uses an LLM to improve accuracy.  You will need to configure the LLM backend - see [below](#llm-services).
+- `--format_lines`: Reformat all lines using a local OCR model (inline math, underlines, bold, etc.).  This will give very good quality math output.
 - `--force_ocr`: Force OCR processing on the entire document, even for pages that might contain extractable text.
 - `--strip_existing_ocr`: Remove all existing OCR text in the document and re-OCR with surya.
+- `--redo_inline_math`: If you want the absolute highest quality inline math conversion, use this along with `--use_llm`.
+- `--disable_image_extraction`: Don't extract images from the PDF.  If you also specify `--use_llm`, then images will be replaced with a description.
 - `--debug`: Enable debug mode for additional logging and diagnostic information.
 - `--processors TEXT`: Override the default processors by providing their full module paths, separated by commas. Example: `--processors "module1.processor1,module2.processor2"`
 - `--config_json PATH`: Path to a JSON configuration file containing additional settings.
