-# Development
+# Build
 
-### 1. Install Flutter
+As part of this project is private, you will be able to run this app from the _main_dev.dart_ file (i.e. --flavor dev). Also to avoid fatal errors the _main_prod.dart_ file is excluded from analysis.
-
-To build this app you need to install Flutter 3.10.0 stable. [How to install](https://docs.flutter.dev/get-started/install).
-
-### 2. (Optional) Install Firebase
-
-Out of the box Firebase Crashlytics won't work. If you want to add Crashlytics to your local build please follow [this guide](https://firebase.google.com/docs/flutter/setup).
-
-### 3. Get packages
-
-As part of the app's functionallity is in the private repo, you have to replace these lines in _pubspec.yaml_:
-
-```yaml
-m3_lightmeter_iap:
-  git:
-    url: "https://github.com/vodemn/m3_lightmeter_iap"
-    ref: main
-```
-with these:
-```yaml
-m3_lightmeter_iap:
-  path: iap
-```
-and run `flutter pub get` from the _iap/_ folder.
-
-Then you can fetch all the neccessary dependencies and generate translation files by running the following commands:
-```console
-flutter pub get
-flutter pub run intl_utils:generate
-```
-
-### 4. Build
-
-You can build an apk by running the following command from the root of the repository:
-```console
-flutter build apk --release --flavor $FLAVOR --dart-define cameraPreviewAspectRatio=2/3 -t lib/main_$FLAVOR.dart
-```
-Just replace `$FLAVOR` with `dev` or `prod`.

 # iOS Limitations
 
 A list of features, that Android version of the app has and that iOS does not.
 
 ## Incident light metering
-
 Apple does not provide API for reading Lux stream form the ambient light sensor. Lux can be calculated based on front camera image stream, but this would be a reflected light. So there is no way incident light metering can be implemented on iOS.
 
 ## Volume buttons action
-
 This can be [implemented](https://stackoverflow.com/questions/70161271/ios-override-hardware-volume-buttons-same-as-zello) but the app will be rejected due to [2.5.9](https://developer.apple.com/app-store/review/guidelines/#software-requirements)
