PSGallery

PSGallery, short for PowerShell Gallery, is the official central repository for PowerShell content, including modules, scripts, and DSC resources. It serves as the primary distribution platform used by PowerShellGet and PackageManagement to publish and discover PowerShell content. The repository is maintained for the benefit of the PowerShell community and includes content from Microsoft as well as independent contributors.

Content in PSGallery is described with metadata such as name, version, description, tags, license, and publisher. Package authors publish their items after creating an account on the PowerShell Gallery, then manage versions and updates through the Publish-Module workflow. Consumers browse and install items to extend PowerShell functionality, with dependencies and compatibility captured in the module manifests.

Access to PSGallery is available via the web at the PowerShell Gallery site and programmatically through PowerShell commands. Typical workflows include Find-Module to discover content, Install-Module to install modules, Update-Module to refresh them, and Publish-Module to publish new or updated content. PSGallery is registered as a repository in PowerShellGet, and users can add or configure it with commands like Register-PSRepository.

Technical details indicate that PSGallery functions as a NuGet-based package feed delivered over HTTPS, with module metadata and versioning supporting discovery and dependency resolution. Content licensing varies by module, and users should review each item’s license and publisher trust before use.

In summary, PSGallery is the central, community-driven hub for distributing and obtaining PowerShell modules, scripts, and resources, enabling streamlined installation and management of shared PowerShell functionality.
