title: Where can i find the documentation for webpack 3?
body: <p>I can't find any documentation for the webpack 3.</p>
  
  <p>Currently I'm using webpack 4 and I wanted to use the <code>extract-text-webpack-plugin</code> which is not supported in webpack 4, so I wanted to downgrade to webpack 3 since the <code>extract-text-webpack-plugin</code> is supported up to that version.</p>
  
  <p>Is there any way I can get the documentation of webpack v3?</p>
