One thing that was greatly missing in the original documentation is any mention on the plugin API, how to create plugins, and even a high level overview on the difference between plugins and loaders. I didn’t see any mention of plugins in this post so would be great to get this in the new docs.

Also you mentioned loaders quite a bit but it seems that between 2.1.0-beta.23 and 2.1.0-beta.25 the loaders and config API had a pretty significant change i.e enhance replacing preLoaders and postLoaders, module.rules as an array of all loaders, and and no longer can loader options be appended to the base webpack config but rather must be added via LoaderOptionsPlugin. It seems difficult to contribute if pieces of the core API are still changing. Should we expect more significant changes of this magnitude in future beta releases?
