+### Options
+
+You can pass the name of the serviceworker file as a parameter with `filename`
+
+```javascript
+var registerServiceWorker = require("serviceworker?filename=anotherserviceworker.js!./sw.js");
+```
+
+By default it adds a hash to the filename so every build it would create a different file. E.g. Would create a file 45fb4c9e6f1e0bd99735.serviceworker.js
+You can remove that has option with the parameter `nohash`.
+
+```javascript
+var registerServiceWorker = require("serviceworker?nohash!./sw.js");
