Note: I am still a noobie with nodejs/yarn/webpack.
I am not sure if the files package.json and yarn.lock could also be removed from the 'dist' package, as the building of the AdminLTEBundle bundle assets is done before a release is made and pushed to github, or if they are necessary, as those assets are built when yarn/webpack are run in the top-level project...

yarn.lock can be removed.
Frontend tooling is not my business as well, so I am not entirely sure if package.json might be used by any tool. I'd say no, but I am not entirely sure, so lets keep it for now.

What about https://github.com/kevinpapst/AdminLTEBundle/tree/master/Resources/docs ?

[gggeek]

I think those should remain included in the dist tarball, as they are useful to the developer who wants to use this bundle
