+# Install-PSModuleHelpers
+
+A GitHub Action to install and configure the PSModule helper modules for use in continuous integration and delivery (CI/CD) workflows. This action is
+a critical component for setting up a standardized PowerShell environment across repositories using the PSModule framework.
+
+This GitHub Action is a part of the [PSModule framework](https://github.com/PSModule). It is recommended to use the
+[Process-PSModule workflow](https://github.com/PSModule/Process-PSModule) to automate the whole process of managing the PowerShell module.

+    branches:
+      - main
+
+jobs:

+          Get-Command -Module Helpers
 ```
+
+## What this action does:
+
+- Removes any existing instances of the `Helpers` module from the PowerShell session.
+- Copies the latest version of the `Helpers` module into the PowerShell module directory.
+- Imports the `Helpers` module, ensuring it is available for subsequent steps.
+
+This action helps maintain consistency and reliability across workflows that depend on the PSModule framework.
