-## Prerequisites
+For general instructions on setting up to do development on this Flutter-based Zulip mobile app, [see the README][readme-link].
+This file covers specific topics in more detail.
 
-Before you begin, you need to setup development environment:

-1. **Flutter SDK**
-   - Follow the [Flutter installation guide](https://docs.flutter.dev/get-started/install) for your platform of choice.
-   - Switch to the latest version of Flutter:
-    ```bash
-    flutter channel master
-    flutter upgrade
-    ```
-   - Ensure Flutter is correctly configured
-    ```bash
-    flutter doctor
-    ```
-
-
-### Flutter version
-
-While in the beta phase, we use the latest Flutter from Flutter's
-main branch.  Use `flutter channel main` and `flutter upgrade`.
-
-We don't pin a specific version, because Flutter itself doesn't offer
-a way to do so.  So far that hasn't been a problem.  When it becomes one,
-we'll figure it out; there are several tools for this in the Flutter
-community.  See [issue #15][].

-## Getting Started
-
-### 1. Clone the Repository
-
-```bash
-git clone https://github.com/zulip/zulip-flutter.git
-cd zulip-flutter
-```
-
-### 2. Install Dependencies
-
-Run the following command to fetch the Flutter dependencies:
-
-```bash
-flutter pub get
-```
-
-### 3. Running the App
-
-To run the app on your local machine, use the following command:
-
-```bash
-flutter run
-```
-
-Ensure that you have an emulator running or a physical device connected.
-
-
-### Tests
-
-You can run all our forms of tests with the `tools/check` script:
-
-```
-$ tools/check
-```
-
-See `tools/check --help` for more information.
-
-The two major test suites are the Dart analyzer, which performs
-type-checking and linting; and our unit tests, located in the `test/`
-directory.
-
-You can run these suites directly with the commands `flutter analyze`
-and `flutter test` respectively.  Both commands accept a list of file
-or directory paths to operate on, and other options.  Particularly
-recommended is a command like
-```
-$ flutter test test/foo/bar_test.dart --name 'baz'
-```
-which will run only the tests in `test/foo/bar_test.dart`,
-and within those only the tests with names matching `baz`.
-
-When editing in an IDE, the IDE should give you the exact same feedback
-as `flutter analyze` would.  When editing a test file, the IDE can also
-run individual tests for you.
-See [upstream docs on `flutter test`][flutter-cookbook-unit-tests].
