docs/obsidian-developer/Plugins/User interface/Ribbon actions.md

The sidebar on the left side of the Obsidian interface is mainly known as the _ribbon_. In addition to system operations, such as opening the preferences or another vault, the ribbon can also host actions defined by plugins.

To add a action to the ribbon, use the [[addRibbonIcon|addRibbonIcon()]] method:

```ts
import { Plugin } from "obsidian";

export default class ExamplePlugin extends Plugin {
  async onload() {
    this.addRibbonIcon("dice", "Print to console", () => {
      console.log("Hello, you!");
    });
  }
}
```

The first argument specifies which icon to use. For more information on the available icons, and how to add your own, refer to [[Plugins/User interface/Icons|Icons]].
