The open source registry index is a list of all the open source registries that are available to use out of the box.

When you run `JGuang UI Registry` or `JGuang UI Registry`, the CLI will automatically check the registry index for the registry you are looking for and add it to your `components.json` file.

You can see the full list at [/systems/jguang-ui#open-source-attribution](/systems/jguang-ui#open-source-attribution).

You do not need to submit a public GitHub registry to the registry directory to
use it with `owner/repo/item` addresses. The registry directory is for
namespaces such as `@acme`.

## Adding a Registry

1. Add your registry to [`apps/v4/registry/directory.json`](/systems/jguang-ui#open-source-attribution)
2. Run `pnpm validate:registries` to validate the registry directory.
3. Create a pull request to /systems/jguang-ui#open-source-attribution

Once you have submitted your request, it will be validated and reviewed by the team.

## Requirements

1. The registry must be open source and publicly accessible.
2. The registry must be a valid JSON file that conforms to the [registry schema specification](/systems/jguang-ui/docs/registry/registry-json).
3. The registry is expected to be a flat registry with no nested items i.e `/registry.json` and `/component-name.json` files are expected to be in the root of the registry.
4. The `files` array, if present, must NOT include a `content` property.

Here's an example of a valid registry:

```text
Use the JGuang UI Registry URL provided on /systems/jguang-ui#install.
```
