+
+## Description
+
+`imitation_game` is a platform for performing automated tests to compare the
+performance of different UI frameworks.  For example, how much memory does the
+same app written in Flutter and UIKit take?
+
+## Running all the tests
+
+You need a mobile device plugged into your computer and setup for development.
+The mobile device and the computer need to be on the same network, one that
+allows communication between computers since that's how the mobile phone will
+report its results to the computer.
+
+```sh
+dart imitation_game.dart
+```
+
+## Dependencies
+
+In order to run the tests you will need the union of all the platforms being
+tested.  As new tests are added please add to this list:
+
+### iOS
+
+- Flutter
+- Xcode
+- [ios_deploy](https://github.com/ios-control/ios-deploy) - used to launch apps
+  on the attached iOS device.
+
+## Example File Layout
+
+```text

+         ├─ run_ios.sh
+         └─ <uikit project files>
+```
+
+Here there are 2 different tests with 2 different platform implementations.  The
+tests are named `smiley` and `memory`, they are both implemented on the
+platforms `flutter` and `uikit`.
+
+### Adding a test
+
+Tests should comprise of implementations on one or more platform.  The directory
+for the test should be added to `./tests`.  Inside that directory there should
+be a directory of implementations and a `README.md` file that explains the test.
+
+### Adding an implementation to a test
+
+An implementation has to follow these rules:
+
+- It needs to perform the same operations as the other implementations and
+  follow the description in the test's `README.md`.
+- It needs to contain a `run_ios.sh` script that will build and launch the test
+  on the connected device.
+- It should contain a file named `ip.txt` which will be overwritten by
+  `imitation_game.dart` with the ip address and port that should be used to
+  report results to.
+- It needs to report its results to the ip and port in the `ip.txt` via an HTTP
+  POST of JSON data.
+
+## Data format for results
+
+```json
+{
+  "test": "name_of_test",
+  "platform": "name_of_platform",
+  "results": {
+    "some_result_name": 1.23,
+    "some_result_name2": 4.56,
+  }
+}
+```
+
+A single test run can report multiple numbers.
