 ### Added
 
 - Added initial support for Python Lambda treeshaking
+  - No more `requirements.txt` necessary in your Python Lambdas, Architect now handles dependency installations automatically upon deployment
+  - Docs: https://arc.codes/docs/en/guides/developer-experience/dependency-management#python
   - This supports global options passed in a root `requirements.txt` file (example: `--extra-index-url https://test.pypi.org/simple/`), but does not yet support dependencies versioned at root, or shared or views dependencies
-  - The `pipdeptree` must be installed in the system and available from shell, so ensure you've run `pip3 install pipdeptree` before using this feature
+  - All project dependencies must be installed on the system prior to deployment
+  - Python Lambda treeshaking also requires the `pipdeptree` package to be available from shell; ensure you've run `pip3 install pipdeptree` prior to use
