-The [`Timeout`](https://github.com/Azure/azure-webjobs-sdk/blob/master/src/Microsoft.Azure.WebJobs/TimeoutAttribute.cs) attribute causes a function to be canceled if it doesn't finish within a specified amount of time. In the following example, the function would run for one day without the Timeout attribute. Timeout causes the function to be canceled after 15 seconds.
+The [`Timeout`](https://github.com/Azure/azure-webjobs-sdk/blob/master/src/Microsoft.Azure.WebJobs/TimeoutAttribute.cs) attribute causes a function to be canceled if it doesn't finish within a specified amount of time. In the following example, the function would run for one day without the Timeout attribute. Timeout causes the function to be canceled after 15 seconds. When the Timeout attribute's "throwOnError" parameter is set to "true", the function invocation is terminated by having an exception thrown by the webjobs SDK when the timeout inverval is exceeded. The default value of "throwOnError" is "false". When the Timeout attribute is used, the default behavior is to cancel the function invocation by setting the cancellation token while allowing the invocation to run indefinitely until the function code returns or throws an exception.
