For CNB, a plugin is a Docker image.

The Plugin Market is a place to aggregate and display plugins for users to query and select.

## Data Source

For the Plugin Market, a plugin data source is a JSON-formatted array, where each entry represents a plugin's information.

In the Admin Panel -> Backend Management -> Feature Configuration -> Document Data Source Management, you can configure multiple data sources by category.

## Example Project

Manually maintaining multiple plugins in a data source JSON file is difficult to manage.

Refer to the [Example Project](https://cnb.cool/examples/ecosystem/plugins-data-source) for guidance.

In a repository, maintain plugins in different directories and use a Pipeline to automatically aggregate them.
