Add some installation hints for Hugo

[iamNoah1]

This may be a small one but on the readme, setting up a local instance assumes that hugo is installed. I think it would be nice to add some info about the prerequisite of hugo that has to be installed at least. Best case IMHO there should also be some info about how to install hugo.

Great point! maybe we can have something like we have in Kubernetes docs:
