+#### build & run
+
+Using bash:
+    $ cd examples/ios
+    $ make run
+
+In an ideal world, this will boot up, install and run the app for the first
+iOS simulator in your `xcrun simctl devices list`. If this fails, you can
+specify the simulator device UUID via:
+    $ DEVICE_ID=${YOUR_DEVICE_ID} make run
+
+If you'd like to see xcode do stuff, you can run
+    $ open bevy_ios_example.xcodeproj/
+
+which will open xcode. You then must push the zoom zoom play button and wait
+for the magic.
+
+The Xcode build GUI will by default build the rust library for both
+`x86_64-apple-ios`, and `aarch64-apple-ios` which may take a while. If you'd
+like speed this up, you update the `IOS_TARGETS` User-Defined environment
+variable in the "`cargo_ios` target" to be either `x86_64-apple-ios` or
+`aarch64-applo-ios` depending on your goal.
+
+Note: if you update this variable in Xcode, it will also change the default
+used for the `Makefile`.
