Umbraco Marketplace

The Umbraco Marketplace is where Umbraco users discover packages. The listing is controlled by two files in the repo root.

umbraco-marketplace.json

Controls the listing metadata. Key fields to maintain:

Field	Purpose	Notes
`Title`	Display name on marketplace	Currently “UmBootstrap”
`VersionSpecificPackageIds`	Maps Umbraco versions to package IDs	Add a new entry for each major Umbraco version
`AuthorDetails`	Author info and contributors	`SyncContributorsFromRepository` auto-pulls from GitHub
`Screenshots`	Listing images	URLs to images (use raw GitHub URLs)
`DocumentationUrl`	Link to docs site	Points to the Starlight docs
`IssueTrackerUrl`	Link to issue tracker	Points to GitHub Issues

umbraco-marketplace-readme.md

Rendered as the package description on the marketplace. The marketplace checks for this file in the repo root — if not found, it falls back to the NuGet package README.

Marketplace README Requirements

The marketplace README has specific constraints:

It must include a warning that the marketplace install buttons don’t support dotnet new template packages — users must follow the CLI or Visual Studio instructions instead
Keep it in sync with README.md (the GitHub version), adding marketplace-specific warnings where needed
Images must use absolute URLs (raw GitHub URLs from the develop branch)

See READMEs for the full picture of how the three READMEs are managed.

Sync Intervals

The marketplace checks for updates automatically:

Check	Interval
New packages	Every 24 hours (0400 UTC)
Package info refresh	Every 2 hours
Download counts	Every 1 hour

No manual step is needed after publishing to NuGet.

Validation

Use the marketplace validation tool to:

Check your umbraco-marketplace.json is valid before publishing
Force a sync if you don’t want to wait for the automatic interval
