Bower is used to manage CSS and JavaScript dependencies. You can upgrade dependencies by specifying a newer version in file `bower.json`. You can also run `bower update` and `bower install` to manage dependencies.
Add the `-h` flag on any command to see how you can use it. For example, `bower update -h`.
For the development of the front-end, the command `grunt serve` can be executed to start a browser-sync session.

Re-run the npm-command, and the zip-file should be used, and extracted to the correct folder.
