+# Contributor Guide
+
+Thank you for your interest in contributing to quality documentations. As an open source project, we
+welcome input and updates from the community.
+
+The process for contributing to this project is documented in our
+[Contributor's Guide](https://aka.ms/PSDocsContributor).
+
+## PowerShell-Docs-DSC structure
+
+There are three categories of content in this repository:
+
+- reference content
+- conceptual content
+- metadata and configuration files
+
+### Reference content
+
+The reference content is the PowerShell cmdlet reference for the DSC cmdlets. The cmdlet reference
+is collected in versioned folders (like dsc-1.1, dsc-2.0, and dsc-3.0). This content is also used to
+create the help information displayed by the `Get-Help` cmdlet.
+
+### Conceptual content
+
+The conceptual documentation is also organized by version.
+
+> [!NOTE]
+> Anytime a conceptual article is added, removed, or renamed, the TOC must be updated and deleted or
+> renamed files must be redirected.
+
+### Metadata files
+
+This project contains several types of metadata files. The metadata files control the behavior of
+our build tools and the publishing system. Only PowerShell-Docs maintainers and approved
+contributors are allowed to change these files. If you think that a meta file should be changed,
+open an issue to discuss the needed changes.
+
+Meta files in the root of the repository
+
+- `.*` - configuration files in the root of the repository
+- `*.md` - Project documentation in the root of the repository
+- `*.yml` - build automation files
+- `.devcontainer/*` - devcontainer configuration files
+- `.github/**/*` - GitHub templates, actions, and other meta files
+- `.vscode/**/*` - VS Code extension configurations
+
+Meta files in the documentation set
+
+- `dsc/**/*.json` - docset configuration files
+- `dsc/**/*.yml` - TOC and other structured content files
