 ## Setup and run Flutter app
 
 - [Setup Flutter based on your operating system](https://flutter.dev/docs/get-started/install)
+
 - Make sure you follow all the steps above and have an all-green output of `flutter doctor` command.
+
 - [Install and run Anroid Studio once](https://developer.android.com/studio/install)
+
 - (For iOS) Install XCode from AppStore
+
 - You can use Android Studio, [IntelliJ Idea](https://www.jetbrains.com/idea/download),
   or [VSCode](https://code.visualstudio.com/download) for Flutter development
+
 - Install Flutter plugin in your chosen IDE
+
 - Clone this repository using `git clone https://github.com/tendermint/flutter.git`
+
 - To run it on your `localhost` environment, you will just have to run `main.dart` file in your project. That can be
   done directly by clicking on the play button in your IDE, or by running `flutter run` from the root of your project.
   This will run the app on any device or simulator connected to your system
+
 - If you're running the app on real device instead of emulator/simulator or want to taget a specific blockchain run on a
-  remote machine, make sure to specify proper urls and ports when running the app. Here is an example for running the
-  app on cosmos hub testnet:
+  remote machine, make sure to specify proper urls and ports when running the app. 
+
+- Edit and update your environment variables in the [`app_config.dart`](https://github.com/tendermint/flutter/blob/main/starport_template/app_config.dart)
+
+- Run the `starport_template` app using `fvm flutter run` or `make run-dev` commands:
 
-```
-flutter run --dart-define=LCD_URL=https://api.testnet.cosmos.network --dart-define=LCD_PORT=443 --dart-define=GRPC_URL=https://grpc.testnet.cosmos.network --dart-define=GRPC_PORT=443
-```
 
 ## Using template from Starport's scaffolded chain
 
 - Clone the [Starport](https://github.com/tendermint/starport) repository from `develop` branch
+
 - Make sure to install [GoLang](https://go.dev/dl/) for your platform
+
 - Run `make install` in Starport's root directory
+
 - Run `starport scaffold chain github.com/cosmonaut/mars` to create a new chain
+
 - Run `cd mars`
+
 - Run `starport scaffold flutter` to create a new Flutter app (this clones the `starport_template` repository - the
   current repo) and puts in under `flutter` subdirectory
+
 - Run `starport generate dart` to generate dart files from proto files to be used by the template to interact with the
   blockchain
