PowerShell Gallery

As explained in Learn PowerShell in a Month of Lunches: Fourth Edition, Covers Windows, Linux, and macOS

PowerShell Gallery is an online repository for discovering and distributing PowerShell modules, scripts, and related packages.

PowerShell Gallery is an online repository for discovering and distributing community-contributed PowerShell modules and related packages. PowerShellGet searches, installs, updates, and registers repositories, much like Linux package managers. Treat downloaded code cautiously: Microsoft operates the gallery but does not validate or endorse every contribution. section 7.2 section 9.2

A practical workflow uses these commands:

• Search with Find-Module, inspect package details and compatibility, then install with Install-Module. section 7.2 section 9.2
• Verify an installed but unloaded module with Get-Module -ListAvailable, and inspect its commands with Get-Command -Module. section 7.2 section 9.2
• Register an internal gallery with Register-PSRepository when private distribution is needed. section 7.2

Find and install a YAML module

Run Find-Module *YAML*, review the results, install powershell-yaml, and use Get-Command -Module powershell-yaml to discover ConvertFrom-Yaml and ConvertTo-Yaml. Review unfamiliar code before trusting it. section 9.2
