## API

Misskey Web exposes APIs for Plugins, which can be used to extend client functionality.
Please refer to the [Plugin API Reference](./plugin-api-reference/) for information on what APIs are available.

## Distributing Plugins

Starting with v2023.11.0, you can install plugins directly from your website with one click.
