Thank you!

[brendankenny]

is the LICENSE file necessary with one at the repo root? Or is this to make sure it's in the npm module? If so, should we add one to chrome-launcher as well?

[samccone]

If someone consumes this module directly then yes for those users it is needed.

Just as FYI, either LICENSE file or license field works for my use case, which is we use license-to-fail to autoscan our deps and fail builds on it and that tool looks in NPM license field or for LICENSE file

Thanks again!
