+# How to contribute to Azure PowerShell reference documentation
+
+Understanding how Azure PowerShell reference documentation is generated and maintained ensures your
+updates are applied correctly and persist across versions.
+
+## What is reference documentation?
+
+Azure PowerShell reference documentation is versioned and autogenerated for each cmdlet in the
+**Az** PowerShell module. It includes:
+
+- Syntax and parameters
+- Usage examples
+- Output descriptions
+
+Docs are generated from the source code and are published once per module version.
+
+> [!IMPORTANT]
+> Changes to the source repo only apply to future versions. Previously published versions must be
+> updated manually.
+
+## How reference docs are generated
+
+Each Azure PowerShell submodule contains source code that defines the behavior and structure of its
+cmdlets. From this codebase:
+
+- A **Markdown help file** is generated per cmdlet, for example,
+  `Update-AzVirtualHubVnetConnection.md`
+- These files live in the [azure-powershell GitHub repo](https://github.com/Azure/azure-powershell)
+- Markdown files are **overwritten** when a developer rebuilds or updates the module
+
+If you're contributing, update both:
+
+1. The Markdown file (for visibility in the repo)
+1. The cmdlet's source code (to ensure your change persists in future releases)
+
+## How reference docs are published
+
+When a new version of **Az** PowerShell module is released:
+
+- A CI process creates a pull request in the
+  [azure-docs-powershell](https://github.com/MicrosoftDocs/azure-docs-powershell) GitHub repo
+- This PR adds generated Markdown files for that version, for example, `azps-13.4.0/Az.Network/`
+- This process runs **once per version**. The Markdown files are **not updated again** automatically
+
+## How to update existing versions
+
+To fix or improve docs for a previously published version:
+
+1. Navigate to the appropriate version folder in this repo, for example `azps-13.4.0/Az.Network/`
+1. Edit the Markdown file directly
+1. Submit a PR for review
+
+> [!NOTE]
+> Reference documentation is versioned and static at publish time. Manual edits are the only way to
+> update content for already-published versions.
