 Experimental support for instant rebuilds using `psc-ide-server` can be enabled
 via the `pscIde: true` option.
 You can use an already running `psc-ide-server` instance by specifying the port in `pscIdeArgs`,
 if there is no server running this loader will start one for you.

-will be appended to `src` parameter.
+When the `watch` option is set to `true`, psc errors are appended to
+webpack's compilation instance errors array and not passed back as an
+error to the loader's callback. This may result in the error not being
+reported by webpack. To display errors, the following plugin may be added
