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`.
