 # Introduction
 
-PDM is a modern Python package manager with [PEP 582] support. It installs and manages packages
+PDM, as described, is a modern Python package and dependency manager supporting the latest PEP standards. But it is more than a package manager. It boosts your development workflow in various aspects. The most significant benefit is it installs and manages packages
 in a similar way to `npm` that doesn't need to create a virtualenv at all!
