Shadergraph isn't an option in the package manager

I want to use Shader Graph but when I go into the package manager to install it isn’t an option in the packs list. I tried uninstalling unity and then reinstalling it but to no avail. Any suggestions? Is there a work around?

So crazy that these dead threads find their way to the stop of SEO lists for idiots like me YEARS LATER.

Also massively annoying.
