+If you're just looking to get up and running quickly, these bash commands will
+fetch packages and set up dependencies (note that the above commands assume
+you're building for both iOS and Android, with both toolchains installed):
+
+```bash
+  #!/bin/bash
+  set -e
+
+  cd flutter_module_using_plugin
+  flutter pub get
+  cd ../flutter_module_books
+  flutter pub get
+  cd ../flutter_module

+  # For iOS builds:
+  flutter build ios-framework --output=../ios_using_prebuilt_module/Flutter
+  cd ../ios_fullscreen
+  pod install
+  cd ../ios_using_plugin
+  pod install
+```
+
+Once those commands have run, you can go into any of the app directories (the
+ones beginning `android_` or `ios_`), and build the apps as you normally would.
