+These features may change significantly and frequently, or they may be
+removed altogether. In some cases, when a feature stabilizes and proves to be
+useful, it may move into the core Lit library.


"it may move into one of the core Lit packages or a new package"?

+From inside your project folder, run:
+
+```bash
+$ npm install lit-labs

is this the right package name? may we update later?

We might want to leave browser support to individual libraries

you might want an export {} for various tools that use that to detect module format, and maybe a console.log("there's nothing here") too.
