You put the human readable part underneath the hash, like `/ipfs/QmPJnEf5933cXteZmaMJkphCW1CtpcMMVx7N6rUr8cZAok/jquery/3.0.0/jquery.js`. In this case, the hash represents a directory of everything from CDNJS and the `jquery/3.0.0/jquery.js` part is a file in that directory. For added readability, there's a thin layer of mutability called IPNS that can map a domain name to a hash, so you could point `cdnjs.com` to `QmPJnEf5933cXteZmaMJkphCW1CtpcMMVx7N6rUr8cZAok` and not have to remember that long ugly hash.
