 Edit Word documents effortlessly and without changing the original formatting of the document. 
 
-As great as the original `docx` library is, this "keep the same format" feature is not natively supported. However, this functionality is pretty useful if you want to automate document writing or editing and need to adhere to strict formatting rules. Hence, I wrote this add-on module.
+The original `docx` library is great but it's missing one important feature: *keeping the original formatting*.
+However, this functionality is pretty useful if you want to automate document writing or editing and need to adhere to strict formatting rules. This is a common requirement in corporate environment for example.

+## Functionalities
 Most of the functions in this module work primarily with **runs**, which are sequences of strings with the same formatting style. Breaking the document into runs allows us to edit the text without changing the original formatting.
 
+Some of the functionalities that this module include:
+- Replacing all occurrences of a string with a new string (optionally limit this up to a paragraph number, and include or exclude tables)
+- Removing a line that includes a specific string
+- Add text to a table
+
+The beauty of this module is that you can use all of its functions to **mass edit** Word documents with consistency and precision. This is useful especially in corporate environments where a lot of document writing or editing can be automated.
