-Install all of the following things:
-
-- [`xcode`](https://apps.apple.com/us/app/xcode/)
+- [`flutter`](https://flutter.dev/docs/get-started/install)
+- [`gomobile`](https://godoc.org/golang.org/x/mobile/cmd/gomobile)

-- [`gomobile`](https://pkg.go.dev/golang.org/x/mobile/cmd/gomobile)
-- [Flutter Android Studio Extension](https://docs.flutter.dev/get-started/editor?tab=androidstudio)
+- [Enable NDK](https://developer.android.com/studio/projects/install-ndk) Check local.properties for current NDK version
 
-Ensure your path is set up correctly to execute flutter
+Currently using flutter 2.0.5
 
-Run `flutter doctor` and fix everything it complains before proceeding
+Copy env.sh.example to env.sh and update your PATH variable to expose both flutter and go bin directories
 
-*NOTE* on iOS, always open `Runner.xcworkspace` and NOT the `Runner.xccodeproj`
+  ```export PATH="$PATH:/path/to/go/bin:/path/to/flutter/bin```
 
-### Before first compile
-
-- Copy `env.sh.example` and set it up for your machine
-- Ensure you have run `gomobile init`
-- In Android Studio, make sure you have the current ndk installed by going to Tools -> SDK Manager, go to the SDK Tools tab, check the `Show package details` box, expand the NDK section and select `21.1.6352462` version.
-- Ensure you have downloaded an ndk via android studio, this is likely not the default one and you need to check the
-  `Show package details` box to select the correct version. The correct version comes from the error when you try and compile
-- Make sure you have `gem` installed with `sudo gem install`
-- If on MacOS arm, `sudo gem install ffi -- --enable-libffi-alloc`
-
-If you are having issues with iOS pods, try blowing it all away! `cd ios && rm -rf Pods/ Podfile.lock && pod install --repo-update`
