Enabling comments module/addon

<%- if @topic_view.topic.tags.present? %>
<%= t 'js.tagging.tags' %>: <%- @topic_view.topic.tags.each do |t| %> <%= t %> <%- end %>
<% end %>

Silverstripe Version: 3.1

Question:

Hello, I’m trying to install the comments module, it appears to be working but only displays a message
https://addons.silverstripe.org/add-ons/silverstripe/comments v 2.1.7

" Post your comment Posting comments has been disabled."

The template shows its missing the <% if $AddCommentForm %>

However I can’t see any documentation on the this area of the configuration, should this be included in the module - once the comments are enabled? or is this something I need to code in myself, to enable the functionality?

The Blog post, has comments setup to load “Allow Comments”

Thanks

Nevermind, missed the obvious just needed to add {$CommentsForm} into the Blog template
