How to override article node content in drupal 8

I have created no of nodes as content type as Article in my website(techladder.in). But I am not getting the right file where I can override the content of the file.

For example, I need to display author information above the Disqus comment section.

I was able to override the node file in my theme at following path: theme/templates/content/node–article.html.twig as following:

     {%   set classes = [         'node',         'node--type-' ~ node.bundle|clean_class,         node.isPromoted() ? 'node--promoted',         node.isSticky() ? 'node--sticky',         not node.isPublished() ? 'node--unpublished',         view_mode ? 'node--view-mode-' ~ view_mode|clean_class,   ] %} {{ attach_library('classy/node') }} <article{{ attributes.addClass(classes) }}>        {{ title_prefix }}   {% if not page %}         <h2{{ title_attributes }}>           <a href="{{ url }}" rel="bookmark">{{ label }}</a>         </h2>   {% endif %}   {{ title_suffix }}        {% if display_submitted %}         <footer class="comment-submitted">           <div{{ author_attributes.addClass('node__submitted') }}>             {% trans %}Submitted by {{ author_name }} on {{ date }}{% endtrans %}             {{ metadata }}           </div>         </footer>   {% endif %}        <div{{ content_attributes.addClass('node__content') }}>         {{ content }}   </div>      </article>  {% if teaser %} <div class="section-divider"><hr class="section-divider"></div> {% endif %} 

But here, I am not able to find a file where I can override the content of the node.

Does anyone has suggestions how can I do it in Drupal 8.
