-### Using styled-components with webpack 2
-
-If you're using `styled-components` with webpack 2 and you use the babel-loader you need to turn off `babel-plugin-transform-es2015-modules-commonjs`. You can do this with a configuration object passed to the es2015 or latest preset.
-
-For `babel-preset-es2015`:
-```JS
-  presets: [
-    ['es2015', {
-      modules: false
-    }]
-  ]
-```
-
-For `babel-preset-latest`:
-```JS
-  presets: [
-    ['latest': {
-      es2015: {
-        modules: false
-      }
-    }]
-  ]
-```
-
-If you can't do this for whatever reason you have to hint webpack to load the commonjs bundle of `style-components`. You can do this by adding this to your webpack configuration:
-
-```JS
-alias: {
-  // Use styled-components commonjs bundle instead of the es modules bundle
-  'styled-components$': 'styled-components/lib/index.js',
-}
-```
-
-In a future version of webpack this bug should be fixed. See [issue#115](https://github.com/styled-components/styled-components/issues/115), [issue#157](https://github.com/styled-components/styled-components/issues/157) and [webpack-issue#3168](https://github.com/webpack/webpack/issues/3168) for further information.

 ### My styles are being repeated multiple times
 
 You might notice that generating styles based on dynamic props will result in repeated CSS declarations. In other words, in the following example:
