 # Vue Flow: Toolbar Component
 
 This is a toolbar component for Vue Flow.
+It can be used to create a floating Toolbar next to your nodes.
+You can either display the Toolbar by setting the visibility prop or automatically showing the Toolbar
+on selected nodes.
+
+## 🛠 Setup

+```bash
+# install
+$ yarn add @vue-flow/node-toolbar
+
+# or
+$ npm i --save @vue-flow/node-toolbar
