 * Job processing with composed modules 
-  - You can use query modules to execute jobs, if the job doesn't error, process an event.
+  - You can use query modules to execute jobs, if the job errors or not, process an event.
   - `with' is similar to `run', the main difference is additional statistics and execution order
+  - when a job completes in error, the event data will contain an additional {error, _} item
 
 To execute a job through the query module, inputting an event on success.
