+# Debugging
+For debugging you should add the following line to conf.php:
+```php
+$modulekit_nocache = true;
+```
+
+Also you should run:
+```sh
+npm run watch
+```
+This is very similar to `npm run build`, but watches JavaScript files for
+changes and will update the dist/openstreetbrowser.js file. Also it will add
+debugging information to the final JavaScript file.
