While you include https://github.com/harvesthq/chosen/blob/master/LICENSE.md, it is missing from https://github.com/harvesthq/chosen-package

In the MIT license itself, it states...

The above copyright notice and this permission notice shall be included in all
copies or substantial portions of the Software.

You are making it MUCH harder for downstream users of this code to meet the licensing requirements when you don't include the LICENSE.md for Bower and NPM builds.
