 ThreePipe has a simple plugin system that allows you to easily add new features to the viewer. Plugins can be added to the viewer using the `addPlugin` and `addPluginSync` methods. The plugin system is designed to be modular and extensible. Plugins can be added to the viewer at any time and can be removed using the `removePlugin` and `removePluginSync` methods.

+
+API Reference: [TonemapPlugin](https://threepipe.org/docs/classes/TonemapPlugin.html)
+
+TonemapPlugin adds a post-processing material extension to the ScreenPass in render manager
+that applies tonemapping to the color. The tonemapping operator can be changed
+by setting the `toneMapping` property of the plugin. The default tonemapping operator is `ACESFilmicToneMapping`.
+
+Other Tonemapping properties can be like `exposure`, `contrast` and `saturation`
+
+TonemapPlugin is added by default in ThreeViewer unless `tonemap` is set to `false` in the options.

+by setting the `dropzone` property to `true` or an object of `DropzonePluginOptions` in the options.

+const viewer = new ThreeViewer({
+  canvas: document.getElementById('mcanvas') as HTMLCanvasElement,
+  dropzone: true, // just set to true to enable drag drop functionatility in the viewer
+})
+```
+
+To set custom options,
+pass an object of [DropzonePluginOptions](https://threepipe.org/docs/interfaces/DropzonePluginOptions.html) type to the `dropzone` property.
+```typescript
+import {DropzonePlugin, ThreeViewer} from 'threepipe'
+const viewer = new ThreeViewer({
+  canvas: document.getElementById('mcanvas') as HTMLCanvasElement,
+  dropzone: { // this can also be set to true and configured by getting a reference to the DropzonePlugin
+    allowedExtensions: ['gltf', 'glb', 'hdr', 'png', 'jpg', 'json', 'fbx', 'obj'], // only allow these file types. If undefined, all files are allowed.

+      autoSetEnvironment: true, // when hdr is dropped
