+# How To Use
+
+There are two commands for the cli tool:
+`init` and `test`
+
+The most common usage is the following:
+
+`npm run init -- --react-native-version next --realm-version latest`
+
+This will create the template for latest release candidate of React Native, install the latest publish `realm` package
+and patch the install test code necessary for the next step.
+
+`npm run test -- --platform ios`
+`npm run test -- --platform android`
+
+This will run test for `ios` and `android` respectively.  The `init` step is required first (without failures).
+This will spawn the app and a server which will be waiting for the application to post a message to.
+When the message has been sent, the test will shutdown and return a success code.
