 # Requirements Interchange Format (ReqIF)
-Java classes to access Specifications & Requirements stored in the Requirements Interchange Format (ReqIF)
+ReqIF (Requirements Interchange Format) is an OMG (Object Management Group) standard for the exchange of requirements between different tools. It is designed to facilitate the transfer of requirements information, ensuring that data can be shared and understood across various platforms and organizations. ReqIF provides a standardized XML format for requirements, making it easier to manage and collaborate on requirements throughout the development lifecycle.
 
-This implementation of the Requirements Interchange Format currently uses http://www.lingala.net/zip4j/ for access to .reqifz files.
+# Project Purpose
+The requirements-interchange-format (ReqIF) library is a parser (and in the future maybe generator) for ReqIF XML documents.
+The classes ReqIF.java and ReqIFz.java can access and decompress ReqIF content for further automation in a Java application.
 
-Fixed old library dependencies.
+This fork is based on https://github.com/bfriebel/requirements-interchange-format and fixed old library dependencies.
+
+# Supported Formats
+ReqIF file extensions .reqif and .reqifz (compressed).
