Closed Unassigned: activate Autoprefixer [118]

Hello,
in the readme.txt of the package Bundle Transformer: Autoprefixer you wrote:
```
To make `AutoprefixCssPostProcessor` is one of the default
CSS-postprocessors, you need to make changes to the Web.config file.
In the `defaultPostProcessors` attribute of
`\configuration\bundleTransformer\core\css` element must be add
`AutoprefixCssPostProcessor` to end of comma-separated list (for
example, `UrlRewritingCssPostProcessor,AutoprefixCssPostProcessor`).
```

The thing is after istalling the package there is no "defaultPostProessors" attribute in my web.config.
Did I missed something?

greetings
