Right now, we have all the resources listed on one page for the directory listing. Would be great if we could partition this into pages of some fixed size.

A clear and concise description of what you want to happen.

Having page listings on the directory listing so that even if we have our API return all entries (i.e. not doing pagination on the backend side as well), at least we have separation into like 20 resources / page so it doesn't cause lag on the page if there are, say, 500 resources.
