+## Autoprefixing
+
+Starting in 6.0.0, Any CSS output via `vue-loader` is piped through [autoprefixer](https://github.com/postcss/autoprefixer) by default. You can customize this behavior in the `vue` section of your webpack config:
+
+``` js
+// webpack.config.js
+module.exports = {
+  // other configs...
+  vue: {
+    // disable autoprefixing
+    autoprefixer: false,
+    // OR: custom options
+    autoprefixer: { browsers: ['last 2 versions'] }
+  }
+}
+```
