 ## Description
 
-Python module to generate Libreoffice documents (ODT and ODS) programatically.
+**UnoGenerator** is a powerful Python module designed to generate LibreOffice documents (ODT and ODS) programmatically with high performance and professional aesthetics.
 
-Morever, you can export them to (.xlsx, .docx, .pdf) easyly.
+Key features include:
+- **Professional Defaults**: Automatic text wrapping (`word_wrap=True`) and vertical centering for professional-looking reports out of the box.
+- **High Performance**: Optimized for large datasets. Inserting 10,000 rows with default formatting takes less than 0.3 seconds.
+- **Rich Exports**: Easy export to `.xlsx`, `.docx`, and `.pdf`.
+- **Advanced Helpers**: Flexible totals generation, automatic column width calculation, and complex data block handling.
+- **Multilingual Support**: Built-in support for translations and localized document generation.
 
-It uses Libreoffice uno module, so you need Libreoffice to be installed in your system.
+It uses the LibreOffice UNO module, requiring a LibreOffice installation on your system.
 
 ## Installation
 
-Only Linux is supported. I'm going to write unogenerator [installation methods](INSTALL.md) for some main Linux Distributions 
+Only Linux is supported. See the [installation guide](INSTALL.md) for detailed instructions on main Linux distributions.
 
+## Architecture
+
+UnoGenerator follows a clean, template-based architecture:
+- **ODS/ODT**: Generic base classes for document manipulation.
+- **ODS_Standard / ODT_Standard**: Optimized subclasses that use the built-in professional templates, providing specific styles (like "Normal", "BoldCenter") and optimized row heights.
 
 ## ODT 'Hello World' example
 
-This is a Hello World example. You get the example in odt, docx and pdf formats:
+Create a professional ODT document with just a few lines:
 
 ```python
 from unogenerator import ODT_Standard
+
 with ODT_Standard() as doc:
-  doc.addParagraph("Hello World", "Heading 1")
-  doc.addParagraph("Easy, isn't it","Standard")
-  doc.save("hello_world.odt")
-  doc.export_docx("hello_world.docx")
-  doc.export_pdf("hello_world.pdf")
+    doc.addParagraph("Hello World", "Heading 1")
+    doc.addParagraph("Easy, isn't it", "Standard")
+    doc.save("hello_world.odt")
+    doc.export_docx("hello_world.docx")
+    doc.export_pdf("hello_world.pdf")
 ```
 
 ## ODS 'Hello World' example
 
-This is a Hello World example. You'll get example files in ods, xlsx and pdf formats:
+Generate a styled spreadsheet with automatic wrapping and alignment:
 
 ```python
 from unogenerator import ODS_Standard
+
 with ODS_Standard() as doc:
-  doc.addCellMergedWithStyle("A1:E1", "Hello world", style="BoldCenter")
-  doc.save("hello_world.ods")
-  doc.export_xlsx("hello_world.xlsx")
-  doc.export_pdf("hello_world.pdf")
+    # word_wrap and vertical alignment are enabled by default
+    doc.addCellMergedWithStyle("A1:E1", "Sales Report 2026", style="BoldCenter")
+    doc.addRowWithStyle("A2", ["Product", "Quantity", "Price", "Total"])
+    doc.save("sales_report.ods")
+    doc.export_xlsx("sales_report.xlsx")
 ```
 
-## Unogenerator scripts
+## Advanced Features: Totals and Formulas
 
-Python unogenerator package has the following scripts:
+UnoGenerator provides advanced helpers to generate calculations quickly:
 
-### unogenerator_monitor
+```python
+from unogenerator import helpers
 
-Monitors your libreoffice server instances
+# Generates both row and column totals with a custom formula template
+helpers.cross_totals_from_range(doc, "B2:D10", key="=SUM({}*1.21)")
+```
 
-### unogenerator_translation
+## Unogenerator scripts
 
-With this tool you can translate several odt files with one command. It generates .pot and .po files, where you can set your translations. Then run your command again and you'll get your files translated
+The package includes several useful CLI tools:
 
-`unogenerator_translation --from_language es --to_language en --input original.odt --input original2.odt  --output_directory "translation_original"`
+### unogenerator_monitor
+Monitors your LibreOffice server instances and their status.
 
-You can use --fake to see simulation of your translation
+### unogenerator_translation
+Translate multiple ODT files using standard `.pot` and `.po` files.
+`unogenerator_translation --from_language es --to_language en --input original.odt --output_directory "translated"`
 
 ### unogenerator_demo
-
-With this tool you can generate a demo, remove its result files and make benchmark comparations in your system
+Generate comprehensive example files and perform performance benchmarks on your system.
 
 ## Documentation
-You can read [documentation](https://github.com/turulomio/unogenerator/blob/main/doc/unogenerator_documentation_en.odt?raw=true) in doc directory. It has been created with unogenerator.
+Full technical [documentation](https://github.com/turulomio/unogenerator/blob/main/doc/unogenerator_documentation_en.odt?raw=true) is available in the `doc` directory, created using UnoGenerator itself.
