 ## Overview
 
-**Parsnips** is a Python tool that analyzes Python source files using the built-in `ast` module and `asttokens` to create fine-grained, reproducible identifiers for fragments of Python code. It is designed to support persistent software identifiers (SWHIDs) for structural code elements such as:
+**Parsnips** is a Python tool that analyzes source files to create a citable hierarchy of folders and metadata files representing nodes in a parsed abstract syntax tree (AST). AST nodes correspond to meaningful code fragments such as classes, functions, and expressions. The metadata files and folders can be stored in your repository. If you archive your repository on Software Heritage, you can then retrieve and cite the SWHIDs for these fragments.
