 Reporters
 ---------
-You can specify a custom reporter as the second argument of the main function, or as the only argument when using a `tsProject`:
+By default, errors are logged to the console and the build crashes on compiler errors. In watch mode, the build does not throw, meaning that consequent builds are still ran. If you do not want to crash the gulp process, you must catch the error. You then need to add `.on('error', () => {})` after `.pipe(tsProject())` or `.pipe(ts(..))`.

 ```javascript
 ts(options, reporter);
 tsProject(reporter);
