 All issues and pull requests are much appreciated! If you are wondering how to build the project:
 
 - torchinfo is actively developed using the lastest version of Python.
-  - Changes should be backward compatible to Python 3.7, and will follow Python's End-of-Life guidance for old versions.
+  - Changes should be backward compatible to Python 3.8, and will follow Python's End-of-Life guidance for old versions.
   - Run `pip install -r requirements-dev.txt`. We use the latest versions of all dev packages.
   - Run `pre-commit install`.
   - To use auto-formatting tools, use `pre-commit run -a`.
