 Remote zip files can be installed by replacing `<zip-file>` with the URL of the hosted file. The tool only supports downloading over HTTP/HTTPS protocols. For local zip files, replace `<zip-file>` with `file:` followed by the absolute or relative path to the plugin zip file as in the second example below.

+### Install a plugin using Maven coordinates
 
 The `opensearch-plugin install` tool also accepts Maven coordinates for available artifacts and versions hosted on [Maven Central](https://search.maven.org/search?q=org.opensearch.plugin). `opensearch-plugin` will parse the Maven coordinates you provide and construct a URL. As a result, the host must be able to connect directly to [Maven Central](https://search.maven.org/search?q=org.opensearch.plugin). The plugin installation will fail if you pass coordinates to a proxy or local repository.
