~It seems yarn does't work well with bs-platform then I suggest we remove the new project creation instructions with yarn~

same issue with new project which is created by using npm

Closing as a duplicate of #35. Some people have had luck upgrading their yarn/npm and bs-platform versions to fix this, although there is no known root cause.
