1. Create a new folder in packages/, let's say with-foo.
2. See package.json in already existing packages and create new with-foo/package.json.
3. Put source code in with-foo/src/, it will be transpiled and bundled into with-foo/dist/, with-foo/lib/ and with-foo/es/.
4. Put tests written with Jest in with-foo/test/.
5. Put demo in with-foo/demo/, it will be rendered and wrapped with HMR.
