Eliminate render-blocking JavaScript and CSS in above-the-fold content

So Goggle tells me to:

Eliminate render-blocking JavaScript and CSS in above-the-fold content

Then it shows a list of js scripts

Next I'm told to

Optimize CSS Delivery

And a bunch more scripts (mostly ES template stuff) are listed.

Ok - I am happy to go and do that. I'd do it immediately except...

I have no idea how! I follow the detailed info links and get garbage details. *sigh*

Seems even Google can't write docs a normal person can understand. LOL

thanks for any push in the right direction,

Bridgette
