-# FundsXML Data Quality Examples
+# FundsXML Enterprise Examples
 
-A comprehensive collection of examples and tools for validating and checking data quality in [FundsXML](https://www.fundsxml.org) documents. This repository helps developers, system integrators, and financial technologists implement FundsXML data validation in their systems.
+A comprehensive, runnable reference for working with [FundsXML](https://www.fundsxml.org) in enterprise settings: sample data across versions and use cases, XSD validation, Schematron, XSLT transformations, XQuery analytics, XML signatures, database integration, large-file streaming, and data binding / JSON — each demonstrated across the common enterprise stacks (CLI, Python, Java, .NET/C#, Node.js) and exercised in CI.
