### About {% data variables.product.prodname_registry %}

{% data variables.product.prodname_registry %} is a platform for hosting and managing packages, including containers and other dependencies. {% data variables.product.prodname_registry %} combines your source code and packages in one place to provide integrated permissions management and billing, so you can centralize your software development on {% data variables.product.product_name %}.

You can integrate {% data variables.product.prodname_registry %} with {% data variables.product.product_name %} APIs, {% data variables.product.prodname_actions %}, and webhooks to create an end-to-end DevOps workflow that includes your code, CI, and deployment solutions.

{% data variables.product.prodname_registry %} offers different package registries for commonly used packages, such as for Node, RubyGems, Apache Maven, Gradle, and Nuget.

{% if currentVersion == "free-pro-team@latest" %}
{% data variables.product.prodname_registry %} also offers a {% data variables.product.prodname_container_registry %} designed to support the unique needs of container images. For more information, see "[About {% data variables.product.prodname_github_container_registry %}](/packages/guides/about-github-container-registry)."

#### Viewing packages

You can review the package's README, some metadata like licensing, download statistics, version history, and more on {% data variables.product.product_name %}. For more information, see "[Viewing packages](/packages/manage-packages/viewing-packages)."

#### About package permissions and visibility

|  | Package registries |
|----|----|
| Hosting locations  | You can host multiple packages in one repository.  |
| Permissions  | Each package inherits the permissions of the repository where the package is hosted. <br> <br> For example, anyone with read permissions for a repository can install a package as a dependency in a project, and anyone with write permissions can publish a new package version. |
| Visibility | {% data reusables.package_registry.public-or-private-packages %} |

{% if currentVersion == "free-pro-team@latest" %}
### About billing for {% data variables.product.prodname_registry %}

{% data reusables.package_registry.packages-billing %} {% data reusables.package_registry.packages-spending-limit-brief %} For more information, see "[About billing for {% data variables.product.prodname_registry %}](/github/setting-up-and-managing-billing-and-payments-on-github/about-billing-for-github-packages)."

{% data reusables.package_registry.container-registry-beta-billing-note %}
{% endif %}

### Supported clients and formats

{% data variables.product.prodname_registry %} uses the native package tooling commands you're already familiar with to publish and install package versions.
#### Support for package registries

{% if currentVersion == "free-pro-team@latest" %}
Package registries use `PACKAGE-TYPE.pkg.github.com/OWNER/REPOSITORY/IMAGE-NAME` as the package host URL, replacing `PACKAGE-TYPE` with the Package namespace. For example, your Gemfile will be hosted at `rubygems.pkg.github.com/OWNER/REPOSITORY/IMAGE-NAME`.

{% else %}

The package types supported on {% data variables.product.product_location %} may vary since your site administrator can enable or disable support for different package types. For more information, see "[Managing GitHub Packages for your enterprise](/enterprise/admin/packages)."

If {% data variables.product.product_location %} has subdomain isolation enabled, then package registries will use `PACKAGE-TYPE.HOSTNAME/OWNER/REPOSITORY/IMAGE-NAME` as the package host URL, replacing `PACKAGE-TYPE` with the Package namespace. For example, your Dockerfile will be hosted at `docker.HOSTNAME/OWNER/REPOSITORY/IMAGE-NAME`.

If {% data variables.product.product_location %} has subdomain isolation disabled, then package registries will use `HOSTNAME/_registry/PACKAGE-TYPE/OWNER/REPOSITORY/IMAGE-NAME` as the package host URL. For example, your Gemfile will be hosted at `HOSTNAME/_registry/rubygems/OWNER/REPOSITORY/IMAGE-NAME`, replacing *HOSTNAME* with the host name of your {% data variables.product.prodname_ghe_server %} instance.

### Authenticating to {% data variables.product.prodname_registry %}

{% data reusables.package_registry.authenticate-packages %}

### About scopes and permissions for package registries

To use or manage a package hosted by a package registry, you must use a token with the appropriate scope, and your user account must have appropriate permissions for that repository.

For example:
-  To download and install packages from a repository, your token must have the `read:packages` scope, and your user account must have read permissions for the repository.
- To delete a specified version of a private package on {% data variables.product.product_name %}, your token must have the `delete:packages` and `repo` scope. Public packages cannot be deleted. For more information, see "[Deleting a package](/packages/manage-packages/deleting-a-package)."

| Scope | Description | Repository permissions |
| --- | --- | --- |
|`read:packages`| Download and install packages from {% data variables.product.prodname_registry %} | read |
|`write:packages`| Upload and publish packages to {% data variables.product.prodname_registry %} | write |
| `delete:packages` | Delete specified versions of private packages from {% data variables.product.prodname_registry %} | admin |
| `repo` | Upload and delete packages (along with `write:packages`, or `delete:packages`) | write, or admin |

When you create a {% data variables.product.prodname_actions %} workflow, you can use the `GITHUB_TOKEN` to publish and install packages in {% data variables.product.prodname_registry %} without needing to store and manage a personal access token.

For more information, see:
- "[Using {% data variables.product.prodname_registry %} with {% data variables.product.prodname_actions %}](/packages/using-github-packages-with-your-projects-ecosystem/)"
- "[Creating a personal access token](/github/authenticating-to-github/creating-a-personal-access-token/)"
- "[Available scopes](/apps/building-oauth-apps/understanding-scopes-for-oauth-apps/#available-scopes)"

### Managing packages

You can delete a version of a private package on {% data variables.product.product_name %} or using the GraphQL API. When you use the GraphQL API to query and delete private packages, you must use the same token you use to authenticate to {% data variables.product.prodname_registry %}. For more information, see "[Deleting a package](/packages/manage-packages/deleting-a-package)" and "[Forming calls with GraphQL](/graphql/guides/forming-calls-with-graphql)."

You can configure webhooks to subscribe to package-related events, such as when a package is published or updated. For more information, see the "[`package` webhook event](/webhooks/event-payloads/#package)."
