Links to webpack 2 documentation

[dmitriid]

The full summary is here: webpack/webpack#1545 (comment) and perhaps here: webpack/webpack#3275

tl;dr version: People would love to learn more about webpack 2 (even if it's a WIP) and help with improving documentation etc. However: there is absolutely no way to discover that the new doc site exists or that it needs help.

Request:

• update webpack's README with a link to the new documentation site. Something like

If you're looking for webpack 2 documentation, go here (work in progress)

• on the front page of webpack 1.x documentation put the same info:

If you're looking for webpack 2 documentation, go here (work in progress)

• on the front page of 2.x documentation clearly state the version the site refers to as in

Documentation site for Webpack 2 (WIP, beta, whatever)

Additionally: add a link to the webpack blog
