+### Min iOS version
+
+Thermion requires a minimum iOS version of 13.0. When building a Flutter application, ensure your application's `ios/Podfile` contains the following:
+
+```ruby
+platform :ios, '13.0'

+
+and in ios/Info.plist:

+When submitting to the App Store, you may encounter an error saying `thermion_dart.framework does not supported the minimum deployment target in Info.plist`. 
+
+This is because Flutter hardcodes a deployment target of iOS 12.0 when invoking the native assets build, which conflicts with actual requirement.
+
+After running `flutter build ios` (but before archiving the build and submitting to the App Store), run the following script to replace the `MinimumOSVersion`:

+## Linux support
+
+Currently, only the Dart package (`thermion_dart`) will work on Linux (primarily for the automated build/testing pipeline). 
+
+Filament has been built for Ubuntu 22.04; other distributions may work, but YMMV.
+
+The Flutter package (`thermion_flutter`) won't work; it's missing the platform glue code necessary to set up the render target.  Support will eventually be added, but there is currently no estimated timeline.

-## Quickstart (Flutter)
+# Quick Start
 
-> You can find the entire project below in the [flutter/quickstart](https://github.com/nmfisher/thermion_examples/tree/master/flutter/quickstart) folder of the `thermion_examples` repository.
+If all you need is a quick and easy route to rendering a single 3D model in your Flutter application, start with `ViewerWidget`.
 
-1. Switch to Flutter master channel, upgrade Flutter, create a new project, then add `thermion_flutter` as a dependency
+This is a simplified, Flutter-only wrapper around the underlying 3D rendering API with sane defaults for most people.
 
-```bash
-$ flutter channel master
-$ flutter upgrade
-$ flutter config --enable-native-assets  
-$ flutter create thermion_sample_project && cd thermion_sample_project
-$ flutter pub add thermion_flutter
-```
+`ViewerWidget` handles all the setup and configuration of the underlying Thermion API, including:
+- Loading 3D models (glTF assets)
+- Configuring skyboxes and image-based lighting
+- Setting up camera positions and manipulators
+- Managing the rendering lifecycle
 
-2. If running on iOS or MacOS, change the minimum deployment target to OSX 13
+## Setup
 
-<Accordion title="Click to open iOS/MacOS instructions">

-
-```yaml
-...

+
+## Camera Manipulators
+
+`ViewerWidget` supports three different camera manipulation modes:
+
+- `ManipulatorType.NONE`: No camera controls, static view
+- `ManipulatorType.ORBIT`: Orbit controls (pinch to zoom, swipe to rotate)
+- `ManipulatorType.FREE_FLIGHT`: Free flight controls for unrestricted movement
+
+Example:
 
 ```dart
+ViewerWidget(
+  assetPath: 'assets/model.glb',
+  manipulatorType: ManipulatorType.FREE_FLIGHT,
+)
+```
 
-class _MyAppState extends State<MyApp> {
+## Lighting
+
+You can set up lighting in multiple ways:
+
+### Image-Based Lighting
+
+```dart
+ViewerWidget(
+  assetPath: 'assets/model.glb',
+  iblPath: 'assets/environment.ktx',
+)
+```
+
+### Direct Light
+
+```dart
+ViewerWidget(
+  assetPath: 'assets/model.glb',
+  directLightType: LightType.SUN,
+)
+```
+
+## Advanced Usage
+
+### Accessing the Viewer
+
+You can get access to the underlying `ThermionViewer` object for more advanced control:
+
+```dart
+ViewerWidget(
+  assetPath: 'assets/model.glb',
+  onViewerAvailable: (viewer) async {
+    // Now you can use the viewer directly
+    final camera = await viewer.getActiveCamera();
+    await camera.lookAt(Vector3(0, 1, 5));
     
-    ThermionViewer? _thermionViewer;
-    void initState() {    
-        _thermionFlutterPlugin.createViewer().then((viewer) {
-            setState(() {
-                _thermionViewer = viewer;
-            });
-        });
-    }    
+    // Add custom lights, manipulate materials, etc.
+  },
+)
+```
 
-    Widget build(BuildContext context) {
-        return Stack(children:[
-            if(_thermionViewer != null)
-            Positioned.fill(
-                child:ThermionWidget(
-                    plugin:_thermionViewer!
-                ) 
-            )
-        ]);  
-    }
+### Changing Manipulator at Runtime
+
+The `manipulatorType` is the only property that can be changed after the widget is created:
+
+```dart
+class _MyWidgetState extends State<MyWidget> {
+  ManipulatorType _manipulatorType = ManipulatorType.ORBIT;
+  
+  @override
+  Widget build(BuildContext context) {
+    return Column(
+      children: [
+        Expanded(
+          child: ViewerWidget(
+            assetPath: 'assets/model.glb',
+            manipulatorType: _manipulatorType,
+          ),
+        ),
+        Row(
+          children: [
+            ElevatedButton(
+              onPressed: () {
+                setState(() {
+                  _manipulatorType = ManipulatorType.ORBIT;
+                });
+              },
+              child: Text('Orbit'),
+            ),
+            ElevatedButton(
+              onPressed: () {
+                setState(() {
+                  _manipulatorType = ManipulatorType.FREE_FLIGHT;
+                });
+              },
+              child: Text('Free Flight'),
+            ),
+          ],
+        ),
+      ],
+    );
+  }
 }
-
 ```
 
-4. Add a button to load the model when pressed
+## Limitations
+
+- Only the `manipulatorType` property can be changed at runtime. For any other property changes, create a new widget.
+- The widget requires that you have the correct environment setup for Thermion (Flutter master channel with native assets enabled).
+
+## Example
+
+Here's a complete example showing how to use `ViewerWidget` with multiple configuration options:
 
 ```dart
+import 'package:flutter/material.dart';
+import 'package:thermion_flutter/thermion_flutter.dart';
+import 'package:vector_math/vector_math_64.dart';
 
-...
-
-class _MyAppState extends State<MyApp> {
-    
-...
-    
-    bool _loaded = false;
-
-    Widget build(BuildContext context) {
-        return Stack(children:[
-            if(_thermionViewer != null)
-            Positioned.fill(
-                child:ThermionWidget(
-                    plugin:_thermionViewer!
-                ) 
-            ),
-            if (!_loaded)
-                Center(
-                    child: ElevatedButton(
-                        child: const Text("Load"),
-                        onPressed: () async {
-                            // TODO 
-                            _loaded = true;
-                            setState(() {});
-                        }))
-        ]);  
-}}
-```
-
-5. When the button is pressed, load a skybox, lighting and the glb asset
-
-You will need to import the `dart:math` and `package:vector_math` libraries.
-
-```dart
-import 'package:vector_math/vector_math_64.dart' as v;
-import 'dart:math';
-
-...
-
-class _MyAppState extends State<MyApp> {
-
-    ...
-
-    Widget build(BuildContext context) {
-        return Stack(children:[
-            ...
-            if(!_loaded)
-                Center(
-                    child: ElevatedButton(
-                        child: const Text("Load"),
-                        onPressed: () async {
-                            var viewer = await _thermionViewer;
-                            await viewer.loadIbl("assets/default_env_ibl.ktx");
-                            await viewer.loadSkybox("assets/default_env_skybox.ktx");
-                            await viewer.loadGlb("assets/cube.glb");
-
-                            await viewer.setCameraPosition(0, 1, 10);
-                            await viewer.setCameraRotation(v.Quaternion.axisAngle(
-                                    v.Vector3(1, 0, 0), -30 / 180 * pi) *
-                                v.Quaternion.axisAngle(v.Vector3(0, 1, 0), 15 / 180 * pi));
-                            await viewer.addLight(
-                                LightType.SUN, 7500, 50000, 0, 0, 0, 1, -1, -1);
-                            await viewer.setRendering(true);
-                            _loaded = true;
-                            setState(() {});
-                        }
-                    )
-                )
-        ]);
-    }
+class ModelViewer extends StatelessWidget {
+  @override
+  Widget build(BuildContext context) {
+    return Scaffold(
+      appBar: AppBar(title: Text('3D Model Viewer')),
+      body: ViewerWidget(
+        assetPath: 'assets/robot.glb',
+        skyboxPath: 'assets/studio_skybox.ktx',
+        iblPath: 'assets/studio_ibl.ktx',
+        initialCameraPosition: Vector3(0, 1.5, 3),
+        manipulatorType: ManipulatorType.ORBIT,
+        showFpsCounter: true,
+        background: Colors.grey,
+        postProcessing: true,
+        transformToUnitCube: true,
+        onViewerAvailable: (viewer) async {
+          // You can perform additional setup here
+          print('Viewer is ready!');
+        },
+      ),
+    );
+  }
 }
-```           
-
-Here, we've added a skybox (the background (cube) image rendered behind all other elements in the scene), image-based lighting (where an image is used to determine the direction and intensity of a light source) and a directional light (Sun).
-
-Anything added to the scene is referred to as an "entity" (including lights and cameras).
-
-Entities are always added to the scene at position (0,0,0).
-
-The default scene camera is located at (0,0,0) (and is looking at -Z, or "into" the screen), so by adding a cube at (0,0,0), the camera will now be inside the cube. 
-
-We need to move the camera outside the cube so it's visible. 
-
-6. Change the camera orientation
-```dart
-   var viewer = await _thermionViewer;
-    await viewer.loadSkybox("assets/default_env_skybox.ktx");
-    await viewer.loadGlb("assets/cube.glb");
-
-    await viewer.setCameraPosition(0, 1, 10);
-    await viewer.setCameraRotation(v.Quaternion.axisAngle(
-                        v.Vector3(1, 0, 0), -30 / 180 * pi) *
-                    v.Quaternion.axisAngle(v.Vector3(0, 1, 0), 15 / 180 * pi));
-```
-
-The cube still won't be visible until we add a light to the scene and tell Thermion to start rendering.
-
-7. Add a light and turn rendering on
-```dart 
-    ...
-    await viewer.addLight(
-                    LightType.SUN, 7500, 50000, 0, 0, 0, 1, -1, -1);
-    await viewer.setRendering(true);
-    ...
-````
-
-8. Run the project
-```
-$ flutter run -d macos
-```
-
-> You may experience a noticeable delay the very first time you run the project. Don't panic, it's not frozen! This is due to the build system downloading the prebuilt Filament binaries from Cloudflare, which can take some time (particularly on Windows). These binaries will be cached after first download, so subsequent runs will be much faster (though every time you run flutter clean, the binaries will be re-downloaded).

+## ThermionViewer (Flutter)
+
+If you just want to display a 3D object in the viewport with some basic camera controls, use the [ViewerWidget described in the Quickstart section](./quickstart).
+
+If you need want more fine-grained control 
+
+> You can find the entire project below in the [examples/flutter/viewer](https://github.com/nmfisher/thermion/tree/master/examples/flutter/viewer) folder of the repository.
+
+
+
+
+
+2. Add a folder containing your assets (glTF model + skybox ktx) to your `pubspec.yaml` asset list
+
+```yaml
+...
+flutter
+  assets:
+    - assets/
+```
+
+3. Create an instance of `ThermionFlutterPlugin` in your app.
+
+```dart
+
+class _MyAppState extends State<MyApp> {
+  late Future<ThermionViewer> _thermionViewer;
+  void initState() {    
+    ThermionFlutterPlugin.createViewer().then((viewer) {
+        _thermionViewer = viewer;
+    });
+  }
+}
+
+```
+
+
+4. Add a `ThermionWidget` to your widget hierarchy 
+
+```dart
+
+class _MyAppState extends State<MyApp> {
+    
+    ThermionViewer? _thermionViewer;
+    void initState() {    
+        _thermionFlutterPlugin.createViewer().then((viewer) {
+            setState(() {
+                _thermionViewer = viewer;
+            });
+        });
+    }    
+
+    Widget build(BuildContext context) {
+        return Stack(children:[
+            if(_thermionViewer != null)
+            Positioned.fill(
+                child:ThermionWidget(
+                    plugin:_thermionViewer!
+                ) 
+            )
+        ]);  
+    }
+}
+
+```
+
+4. Add a button to load the model when pressed
+
+```dart
+
+...
+
+class _MyAppState extends State<MyApp> {
+    
+...
+    
+    bool _loaded = false;
+
+    Widget build(BuildContext context) {
+        return Stack(children:[
+            if(_thermionViewer != null)
+            Positioned.fill(
+                child:ThermionWidget(
+                    plugin:_thermionViewer!
+                ) 
+            ),
+            if (!_loaded)
+                Center(
+                    child: ElevatedButton(
+                        child: const Text("Load"),
+                        onPressed: () async {
+                            // TODO 
+                            _loaded = true;
+                            setState(() {});
+                        }))
+        ]);  
+}}
+```
+
+5. When the button is pressed, load a skybox, lighting and the glb asset
+
+You will need to import the `dart:math` and `package:vector_math` libraries.
+
+```dart
+import 'package:vector_math/vector_math_64.dart' as v;
+import 'dart:math';
+
+...

+            ...
+            if(!_loaded)
+                Center(
+                    child: ElevatedButton(
+                        child: const Text("Load"),
+                        onPressed: () async {
+                            var viewer = await _thermionViewer;
+                            await viewer.loadIbl("assets/default_env_ibl.ktx");
+                            await viewer.loadSkybox("assets/default_env_skybox.ktx");
+                            await viewer.loadGlb("assets/cube.glb");
+
+                            await viewer.setCameraPosition(0, 1, 10);
+                            await viewer.setCameraRotation(v.Quaternion.axisAngle(
+                                    v.Vector3(1, 0, 0), -30 / 180 * pi) *
+                                v.Quaternion.axisAngle(v.Vector3(0, 1, 0), 15 / 180 * pi));
+                            await viewer.addLight(
+                                LightType.SUN, 7500, 50000, 0, 0, 0, 1, -1, -1);
+                            await viewer.setRendering(true);
+                            _loaded = true;
+                            setState(() {});
+                        }
+                    )
+                )
+        ]);
+    }
+}
+```           
+

 ## Windows
 
-## CMakeLists
-
-You will need to disable the `/WX` compiler flag.
-
-In your project, open the `windows/CMakeList.txt` file and find the following line:
-
-`target_compile_options(${TARGET} PRIVATE /W4 /WX /wd"4100")`
-
-Delete the `/WX`:
-
-`target_compile_options(${TARGET} PRIVATE /W4 /wd"4100")`
-
-
-## pubspec.yaml
-
-On Windows, you will need to add a custom version of `native_toolchain_c` to your `dependency_overrides`. This is currently needed to link static libraries when building a DLL.
-
-```
-dependency_overrides:
-  native_toolchain_c:
-    git:
-      url: https://github.com/nmfisher/native.git
-      path: pkgs/native_toolchain_c
-      ref: windows_dll_fix
-```
-
-This will eventually be fixed upstream in the `native_toolchain_c` package, so this should be a short-term/temporary issue only.
+If you're not a Thermion developer, you can ignore this.
 
 ## ANGLE build (not currently working)
 To support embedding GPU textures in Flutter (rather than copying to a CPU pixel buffer on every frame), we need to build a slightly customized version of Filament that uses GLES on Windows (rather than the default, which uses OpenGL).
