Making it possible to run integration tests against any Firebase project

 To run the integration test suite:

-$ node test/integration   # Run integration test suite
+$ node test/integration <apiKey>   # Run integration test suite
 ```
 
-The integration test suite requires you to generate a service account key JSON file for the
-**admin-sdks-test** Firebase project and save it to `test/resources/key.json`. You can generate this
-from the
-[**Service Accounts**](https://console.firebase.google.com/project/admin-sdks-test/settings/serviceaccounts/adminsdk)
-tab of that project's settings page.
+The integration test suite requires you to generate a service account key JSON file for a
+Firebase project and save it to `test/resources/key.json`. Create a new project in the
+[Firebase console](https://console.firebase.google.com) if you do not already have one.
+Use a separate, dedicated project for integration tests since the test suite makes a large
+number of writes to the Firebase realtime database. Download the service account key file
+from the "Settings > Service Accounts" page of the project, and copy it to
+`test/resources/key.json`. Also obtain the API key for the same project from "Settings > General".
+This API key should be passed into the test suite as a command-line argument.
