Windows instructions broken. Link to editor-shared repo broken.

Hi,

The windows installation instructions state:

Since symlinks may not work on Windows, also clone https://github.com/serenadeai/editor-shared and replace the src/shared symlink here with the contents of editor-shared/src.

The https://github.com/serenadeai/editor-shared repo does not exist though.

Thanks!

P.S. Similar issue in #4
