+## Web and Desktop support
+With the introduction of Flutter 2.0 it is now possible to create web and desktop applications with Flutter, and this is no different when you're using `Rosetta`.
+
+### Web
+Please make sure you meet the following requirements:
+https://flutter.dev/docs/get-started/web#requirements
+
+Once you've made sure you meet the requirements, you can check what browsers you have available by running the following command and observing the output:
+```
+flutter devices
+```
+Afterwards, you can use the following command to serve your app on `localhost`:
+
+```
+flutter run -d <browser>
+```
+where `<browser>` is a browser previously listed by ```flutter devices``` that you want to use (e.g. `chrome` / `edge` / etc) .
+
+
+And the following command to build your app as a web app:
+```
+flutter build web
+```
+
+### Desktop
+Please make sure you meet the following requirements:
+https://flutter.dev/desktop#requirements
+
+Once you've made sure you meet the requirements, you can use the following command to enable desktop support for a platform for your app:
+```
+flutter config --enable-<platform>-desktop
+```
+where `<platform>` is one of the following: `windows` / `macos` / `linux`
+(e.g. `flutter config --enable-macos-desktop`)
+
+To ensure that desktop _is_ enabled, list the devices available by running
+```
+flutter devices
+```
+ You should see Windows, macOS, or Linux, depending on which platforms you’ve enabled.
+
+After you've successfully enabled desktop support for one (or more) of the aforementioned platforms, you can run the following command to launch your application:
+ ```
+flutter run -d <platform>
+```
+where `<platform>` is one of the following: `windows` / `macos` / `linux`
+(e.g. ```flutter run -d windows```)
+
+To generate a release build, run the following command:
+```
+flutter build <platform>
+```
+where `<platform>` is your platform of choice, e.g. `flutter build macos`.
+
+
+For more information, please refer to the official Flutter documentation:
