how to 'Add a Filter to your content_browser'

[falkorichter]

This documentation is not conclusive:

scrivito.content_browser.filters = {
  obj_class: {
    field: '_obj_class',
    options: {
      Quote: {
        title: 'Quote',
        icon: 'person',
        query: scrivito.obj_where('_obj_class', 'equals', 'Quote'),
        enable_create: true,
        preset: {
          _obj_class: 'Quote'
        }
      }
    }
  }
};

Where do I add it?
Where is the content_browser documentation? https://rubygems.org/gems/scrivito_content_browser is referencing https://scrivito.com/d81bd1bfdd4afe2b/content-browser-overview which is not the developer documentation the "Homepage" link is broken http://www.scrivito.com/ as well

I see there is some developer documentation on the content_browser... but The Sample project we were told to start with (and did) does not contain any coffee script files
