-## Troubleshooting

-#### Blank preview window
-
-Certain setups (for example when using `Rack::LiveReload`) can cause an issue with the way that the preview iframe displays the rendered component preview (i.e. using the `srcdoc` attribute to avoid extra requests).
-
-If you are seeing a blank preview window, but the source and output tabs are both displaying code as expected, you can disable the use of the `srcdoc` attribute using the following configuration option:
-
-```ruby
-config.lookbook.preview_srcdoc = false
-```

 ## Contributing
 
 Lookbook is very much a small hobby/side project at the moment. I'd love to hear from anyone who is interested in contributing but I'm terrible at replying to emails or messages, so don't be surprised if I take forever to get back to you. It's not personal 😜
