Has any one  used FFCRM with Slim? What steps do I need to follow to use slim in the application.
- if (template = template_for_current_view)
  | list
  = render(template, :account => @account)
- else
  / default view
  = styles_for :task, :contact, :opportunity, :lead, :invoice
  = render 'accounts/title_bar', :account => @account
  div#edit_account
  = render "comments/new", :commentable => @account
  = render :partial => "shared/timeline", :collection => @timeline
  | Before hook
  = hook(:show_account_bottom, self, {entity: @account}) do
    | Inside hook
    = render :partial => "tasks/tasks", :locals => {:object => @account}
    = render partial: "contacts/contacts", :object => @account
    = render "leads/leads", :object => @account
    = render "opportunities/opportunities", :object => @account
    - if @account.supplier?
      = render "invoices/invoices", collection: @bills, category: 'bills'
    = render "invoices/invoices", collection: @invoices, category: 'invoices'
    = render "versions/versions", :object => @account
    = load_select_popups_for(@account, :tasks, :contacts, :opportunities)
