+const Plugin = require('@uppy/core/lib/plugin')
+const ProviderViews = require('@uppy/provider-views')
+
+class GoogleDrive extends Plugin {
+  constructor () { /* snip */ }
+  install () {
+    this.view = new ProviderViews(this)
+    // snip
+  }
+
+  render (state) {
+    return this.view.render(state)
+  }
+}
+```
+
+## Installation
+
+> Unless you are creating a custom provider plugin, you do not need to install this.
