+There are many use cases that require the identification of package software 
+dependencies including:
+- Identifying the licenses and vulnerabilites from package dependencies before you select a software package to use it in your product or project.
+- Identifying package version dependencies before you upgrade a package.
+- Reporting package dependencies with their licenses or vulnerabilities in an SBOM or other document.
+
+- **ScanCode Toolkit** and **ScanCode.io** both collect and report package
+dependency data from package manifest and dependency lock files (e.g., package.json or package-lock.json for npm. The reported package data includes the scope of a dependency and related attributes (runtime, optional, pinned, direct). 
+- [dependency inspector](https://github.com/aboutcode-org/dependency-inspector/blob/main/README.rst) is a command line tool to generate package lockfiles and parsable package manifests to make it easy to collect resolved dependencies 
+and accurate metadata for a project. It uses the standard package management tool for each package type or ecosystem.
+- [nuget-inspector](https://github.com/aboutcode-org/nuget-inspector/blob/main/README.rst) is a utility to resolve .NET or nuget package dependencies independently of a dotnet SDK installed on the computer used to run the **nuget-inspector**.
+- [python-inspector](https://github.com/aboutcode-org/python-inspector/blob/main/README.rst) is utility to resovlve PyPI package dependencies and query PyPI 
+to enrich package metadata.
