+
+there are some further steps you may need to implement in order to get rollbar.js working for you. 
+
+When compiling, if you get the error `Error encountered resolving symbol values statically. Function calls are not supported. Consider replacing the function or lambda with a reference to an exported function`, then the inline factory function in providers should be an exported function.
+
+Another error you may encounter when compiling is `Property 'error' does not exist on type '{}'.` In this case, the RollbarErrorHandler `var rollbar` needs to have a type explicitly defined, i.e. `var rollbar: Rollbar`.
