 Notes:
 - If parameter `reportPerMin` is equal to 0, there is no limit on the number of error reports per minute. When the `reportPerMin` cap is reached, `BacktraceClient.Send/BacktraceClient.SendAsync` method will return false,
+- If you develop application behind the proxy you can pass `WebProxy` object to `BacktraceCredentials` object. We will try to use `WebProxy` object when user pass it to `Backtrace`. To setup proxy use property `Proxy`,
 - `BacktraceClient` allows you to unpack `AggregateExceptions` and send only exceptions that are available in `InnerException` property of `AggregateException`. By default `BacktraceClient` will send `AggregateException` information to Backtrace server. To avoid sending these reports, please override `UnpackAggregateException` and set value to `true`.
