Please see the "[Getting an Application Insights Instrumentation Key](https://github.com/Microsoft/AppInsights-Home/wiki#getting-an-application-insights-instrumentation-key)" section of the wiki for more information. To try the SDK without an instrumentation key, set the instrumentationKey config value to a non-empty string.
