 ## Capabilities
 
-- Uses your configured NuGet feeds to get real time information about packages.
-- Provides the ability to update packages with known vulnerabilities, including transitive dependencies.
-- Provides advanced tooling for updating packages which provides the best updates based on a projects unique package graph and target frameworks.
+- Uses your configured NuGet feeds to get real-time information about packages.
+- Provides conservative remediation planning for packages with known vulnerabilities, including transitive dependencies.
+- Provides package upgrade planning based on a project's package graph and target frameworks.
+- Reviews your repository's NuGet supply-chain posture (Central Package Management, NuGet Audit, Package Source Mapping, and `NuGet.Config` validity) and recommends hardening steps.
