The organization of the lit-html and lit-element packages didn't change: they're separate and lit-element depends on lit-html. The only difference is that we added the lit package that rolls them both up and we talk about templating in one place in the docs rather than two (lit-html and lit-element used to have separate sites). We did this because most people used lit-element and the separation was confusing to some and a little bit of rough DX for most.
