Change 'browse' to 'All categories' as it is more meaningful to users even if they for some reason end up on /browse where they shouldn't really be
user
```ruby
class BrowseController < ApplicationController

  def index
    setup_page_title("All categories")
    options = {title: "browse", section_name: "Browse", section_link: "/browse"}
    set_slimmer_dummy_artefact(options)
  end

  def section
    @category = content_api.tag(params[:section])
    response = content_api.sub_sections(params[:section])
    @sub_categories = response.results
    setup_page_title(@category.title)
    options = {title: "browse", section_name: "#{@category.title}", section_link: "/browse/#{params[:section]}"}
    set_slimmer_dummy_artefact(options)
  end

  def sub_section
    tag_id = "#{params[:section]}/#{params[:sub_section]}"
    @sub_category = content_api.tag(tag_id)

    @category = @sub_category.parent
    @results = content_api.sorted_by(tag_id, "alphabetical").results

    setup_page_title(@sub_category.title)

              parent: {section_name: @category.title,
                      section_link: "/browse/#{params[:section]}"},
